Subject: [PATCH] scsi: fnic: remove redundant assignment of variable rc

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

Variable ret is initialized to a value that is never read and it is
re-assigned later and immediatetly returns. Clean up the code by
removing rc and just returning 0.

Addresses-Coverity: ("Unused value")
