scsi: aacraid: Allow reset_host sysfs var to recover Panicked Fw
It is possible to restart the controller via the use of the reset_host
sysfs variable. This does work for controllers that can no longer respond,
since driver will attempt to send down a shutdown in this path.
Check if the controller is able to receive commands before sending down
a shutdown
