After reset completed, the scsi error handler sends out START_STOP
and TEST_UNIT_READY to the device. For 'normal' devices these
commands will be handled by firmware. However, because the RAID
console only interfaces to scsi mid layer, the firmware will not process
these commands for it. This will make the console to be offlined right
after reset. Add the handling in driver to fix this problem.
