scsi: mpi3mr: Split off bus_reset function from host_reset
SCSI EH host reset is the final callback in the escalation chain; once we
reach this we need to reset the controller. As such it defeats the purpose
to skip controller reset if no I/Os are pending and the RAID device is to
be reset; especially after kexec there might be stale commands pending in
firmware for which we have no reference whatsoever. So this patch splits
off the check for pending I/O into a 'bus_reset' function, and leaves the
actual controller reset to the host reset.
