This routine transitions the device to the SDEV_BLOCK state
(which must be a legal transition).  When the device is in this
state, all commands are deferred until the scsi lld reenables
the device with scsi_device_unblock or device_block_tmo fires.
This routine assumes the host_lock is held on entry.
