cifs: use workqueue instead of slow-work
Workqueue can now handle high concurrency. Use system_nrt_wq instead of slow-work. * Updated is_valid_oplock_break() to not call cifs_oplock_break_put() as advised by Steve French. It might cause deadlock. Instead, reference is increased after queueing succeeded and cifs_oplock_break() briefly grabs GlobalSMBSeslock before putting the cfile to make sure it doesn't put before the matching get is finished. * Anton Blanchard reported that cifs conversion was using now gone system_single_wq. Use system_nrt_wq which provides non-reentrance guarantee which is enough and much better.
