Mike Christie 4cf1043593 [SCSI] libiscsi regression in 2.6.25: fix nop timer handling
The following patch fixes a bug in the iscsi nop processing.
The target sends iscsi nops to ping the initiator and the
initiator has to send nops to reply and can send nops to
ping the target.

In 2.6.25 we moved the nop processing to the kernel to handle
problems when the userspace daemon is not up, but the target
is pinging us, and to handle when scsi commands timeout, but
the transport may be the cause (we can send a nop to check
the transport). When we added this code we added a bug where
if the transport timer wakes at the exact same time we are supposed to check
for a nop timeout we drop the session instead of checking the transport.

This patch checks if a iscsi ping is outstanding and if the ping has
timed out, to determine if we need to signal a connection problem.
