  cifs: fix workstation_name for multiuser mounts (2022-02-03 00:16:37 -0600)

----------------------------------------------------------------
SMB3 client fixes including:
- multiple fscache related fixes, reenabling ability to read/write to
cached files for cifs.ko
  (that was temporarily disabled for cifs.ko a few weeks ago due to
the recent fscache changes)
    - also includes a new fscache helper function ("query_occupancy")
used by above
- fix for multiuser mounts and NTLMSSP auth (workstation name) for stable
- fix locking ordering problem in multichannel code
- trivial malformed comment fix

Unit test results:

There is an additional DFS reconnection fix, unrelated to this, still
being worked on, that is not included in this P/R
