Subject: [PATCH] cifs: remove redundant assignment to variable rc

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

Variable rc is being initialized with a value that is never read
and rc is being re-assigned a little later on. The assignment is
redundant and hence can be removed.

Addresses-Coverity: ("Unused value")
