  smb3: prevent races updating CurrentMid (2021-06-25 14:02:26 -0500)

----------------------------------------------------------------
38 cifs/smb3 fixes including:
- improvement to fallocate emulation
- 9 DFS fixes
- 2 minor multichannel fixes
- Various cleanup patches, many to address Coverity warnings

There are various features still being tested that are not included
in this PR but that should be ready soon, including some important
multichannel fixes, support for the new signing negotiate context as
well as an important multiuser uid fix.  We are also still working on
the switchover to netfs for readahead so that is not included in this
series yet.
