cifs: on multiuser mount, set ownership to current_fsuid/current_fsgid (try #7)
commit 3aa1c8c2900065a51268430ab48a1b42fdfe5b45 made cifs_getattr set
the ownership of files to current_fsuid/current_fsgid when multiuser
mounts were in use and when mnt_uid/mnt_gid were non-zero.
It should have instead based that decision on the
CIFS_MOUNT_OVERR_UID/GID flags.
