scsi: lpfc: fix missing spin_unlock on sql_list_lock

Browse Source 
From: Colin Ian King <colin.king@canonical.com>

In the case where sglq is null, the current code just returns without
unlocking the spinlock sql_list_lock. Fix this by breaking out of the
while loop and the exit path will then unlock and return NULL as was
the original intention.

Detected by CoverityScan, CID#1411635 ("Missing unlock")
