esp: check for NULL result from scsi_device_find()

Add a 'current_lun' check for a null value
to avoid null pointer dereferencing and
recover host if NULL return

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 4eb8606560 (esp: store lun coming from the MESSAGE OUT phase)
