scsi: scsi_debug: Drop scsi_debug_host_reset() device NULL pointer check 

The check for device pointer for the SCSI command is unnecessary, so drop
it.

The only caller is scsi_try_host_reset() -> eh_host_reset_handler(), and
there that pointer cannot be NULL.

Indeed, there is already code later in the same function which does not
check the device pointer for the SCSI command.
