io_uring: fix io_sqe_files_unregister() hangs
commit 1ffc54220c444774b7f09e6d2121e732f8e19b94 upstream.
io_sqe_files_unregister() uninterruptibly waits for enqueued ref nodes,
however requests keeping them may never complete, e.g. because of some
userspace dependency. Make sure it's interruptible otherwise it would
hang forever.
