fsnotify: Remove special handling of mark destruction on group shutdown
Currently we queue all marks for destruction on group shutdown and then destroy them from fsnotify_destroy_group() instead from a worker thread which is the usual path. However worker can already be processing some list of marks to destroy so this does not make 100% all marks are really destroyed by the time group is shut down. This isn't a big problem as each mark holds group reference and thus group stays partially alive until all marks are really freed but there's no point in complicating our lives - just wait for the delayed work to be finished instead.
