Mitchell Horne 4eb861d362 shutdown: audit shutdown_post_sync event callbacks 
Ensure they are all panic/debugger safe.

Most handlers for this event are for disk drivers/geom modules. There
are a mix of checks being used here (or not), so let's standardize on
checking the presence of the RB_NOSYNC flag.

This flag is set whenever:
 1. The kernel has panicked and kern.sync_on_panic=0*
 2. We reboot from within the kernel debugger (the "reset" command)
 3. Userspace requested it, e.g. by 'reboot -n'

Name the functions consistently.

*This sysctl is tuned to zero by default, but its existence means that
these handlers can be executed after a panic, at the user's discretion.
IMO this use-case is implicitly understood to be risky, and we'd be
better off eliminating it altogether.
