fanotify: fix false positive on permission events
fsnotify_get_mark_safe() may return false for a mark on an unrelated group,
which results in bypassing the permission check.
Fix by skipping over detached marks that are not in the current group.

Fixes: abc77577a669 ("fsnotify: Provide framework for dropping SRCU lock in ->handle_event")
