Consistently use the weird ssize_t type for things I know are unsigned,
but which none-the-less need to be compared to signed things to prevent
a bogus warning. Sigh, these aren't bugs, can't possibly be bugs and
a waste of time to fix.

This produces the same data as the Linux nvme-cli 'nvme telemetry-log'
command. It extracts the telemetry log from drive. This is a variable
length log, so we read the first page and find out how much of the log
to grab. There's 3 levels of details available, and we grab the level of
detail specified on the command line.

In this case it is harmless since it is an array of pointers so the
resulting length is identical.

Even though mqes (uint16_t) and queue_size (u_int) are both unsigned,
the expression 'mqes + 1' gets promoted to int which is signed. Keep
the value unsigned by explicitly promoting mqes to u_int before
incrementing the value.

- discover: Connects to a remote Discovery controller, fetches its
Discovery Log Page, and enumerates the remote controllers described
in the log page.
The -v option can be used to display the Identify Controller data
structure for the Discovery controller. This is only really useful
for debugging.
- connect: Connects to a remote I/O controller and establishes an
association of an admin queue and a single I/O queue. The
association is handed off to the in-kernel host to create a new
nvmeX device.
- connect-all: Connects to a Discovery controller and attempts to
create an association with each I/O controller enumerated in the
Discovery controller's Discovery Log Page.
- reconnect: Establishes a new association with a remote I/O
controller for an existing nvmeX device. This can be used to
restore access to a remote I/O controller after the loss of a prior
association due to a transport error, controller reboot, etc.
- disconnect: Deletes one or more nvmeX devices after detaching its
namespaces and terminating any active associations. The devices to
delete can be identified by either a nvmeX device name or the NQN of
the remote controller.
- disconnect-all: Deletes all active associations with remote
controllers.

The format command takes a number of different parameters. Include a
brief summary of what the values mean, though since the driver's support
for metadata is at best weak, 0's are almost always used for values
other than -f format. Add an example that ties it all together.

The manpage of nvmecontrol(8) has the following SYNOPSIS:
nvmecontrol format [-f fmt] [-m mset] [-o pi] [-l pil] [-E]
[-C] <device-id | namespace-id>
The correct switch for the pi option is -p according
to sbin/nvmecontrol/format.c:
OPT("pi", 'p', arg_uint32, opt, pi, "Protective information")
So correct the SYNOPSIS section accordingly.
