When we are in connection recovery and the internal command timer on a request pops, either the scsi_cmnd->device or scsi_cmnd->device->host back pointers may be NULL as the device that the command that the request was submitted on may have been subsequently reaped due to the connection recovery. This can cause one or both of the pointers above to be NULL and cause a system crash if we try
to return the command to the midlayer.

Instead, double check the pointers before the return to the midlayer so as to prevent the crash and let the upper layers finish the session recovery and
rediscover the device.
