Subject: [PATCH] scsi: qla2xxx: remove redundant null check on pointer sess

From: Colin Ian King <colin.king@...onical.com>

The null check on pointer sess and the subsequent call is redundant
as sess is null on all the the paths that lead to the out_term2 label.
Hence the null check and the call can be removed.

Detected by CoverityScan, CID#1420663 ("Logically dead code")
