[PATCH] scsi_transport_fc: remove useless check

[Andrzej Hajda <a.hajda@samsung.com>]

simple_strtoul returns only non-negative values and *val is unsigned
so there is no possibility that *val is lesser than 0.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci [1].
