[PATCH] [SCSI] target: Remove unneeded test of se_cmd

[Roland Dreier <rdreier@cisco.com>]

se_cmd is dereferenced unconditionally in many other parts of
transport_get_lun_for_cmd() so remove the last test whether se_cmd is NULL.

I'm not 100% sure of this patch (perhaps se_cmd can be NULL here and the
whole rest of the function needs to be fixed instead), but this seems
like the more sensible thing.
