cifs: return proper error code in statfs(2)

commit 14302ee3301b3a77b331cc14efb95bf7184c73cc upstream.

In cifs_statfs(), if server->ops->queryfs is not NULL, then we should
use its return value rather than always returning 0.  Instead, use rc
variable as it is properly set to 0 in case there is no
server->ops->queryfs.
