Amir Goldstein b74063b5f1 fanotify: update connector fsid cache on add mark

commit c285a2f01d upstream.

When implementing connector fsid cache, we only initialized the cache
when the first mark added to object was added by FAN_REPORT_FID group.
We forgot to update conn->fsid when the second mark is added by
FAN_REPORT_FID group to an already attached connector without fsid
cache.
