fuse: fix hang of single threaded fuseblk filesystem
commit 5a18ec176c934ca1bc9dc61580a5e0e90a9b5733 upstream.
Single threaded NTFS-3G could get stuck if a delayed RELEASE reply
triggered a DESTROY request via path_put().
Fix this by
a) making RELEASE requests synchronous, whenever possible, on fuseblk
filesystems
b) if not possible (triggered by an asynchronous read/write) then do
the path_put() in a separate thread with schedule_work().
