target: Fix target_sense_desc_format NULL pointer dereference

This patch allows target_sense_desc_format() to be called without a
valid se_device pointer, which can occur during an early exception
ahead of transport_lookup_cmd_lun() setting up se_cmd->se_device.

This addresses a v4.3-rc1 specific NULL pointer dereference
regression introduced by commit 4e4937e8.
