Subject: [PATCH] Don't log expected error on DFS referral request
Git-commit: 2564f2ff83975e05dbd2f13301f7147b63e67c91
Patch-mainline: v4.17-rc1
References: bsc#1051510, bsc#1144333
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.
