cifs: Fix lookup of root ses in DFS referral cache
We don't care about module aliasing validation in
cifs_compose_mount_options(..., is_smb3) when finding the root SMB

Nov 08 15:27:08 tw kernel: [kworke] call request_key(,FS0.WIN.LOCAL,)
Nov 08 15:27:08 tw kernel: [kworke] ==> dns_resolver_cmp(FS0.WIN.LOCAL,FS0.WIN.LOCAL)
