STATUS_FS_DRIVER_REQUIRED is expected when DFS is not turned
on on the server. Do not log it on DFS referral response.
It clutters the dmesg log unnecessarily at mount time.

Subject: [PATCH] [SMB3] Don't log expected error on DFS referral request
STATUS_FS_DRIVER_REQUIRED is expected when DFS is not turned
on on the server. Do not log it on DFS referral response.
It clutters the dmesg log unnecessarily at mount time.
