  CIFS: Fix task struct use-after-free on reconnect (2020-01-26 19:24:17 -0600)

----------------------------------------------------------------
   - Various SMB3/CIFS fixes including 4 for stable.
   - Improvement to fallocate (enables 3 additional xfstests)
   - Fix for file creation when mounting with modefromsid
   - Add ability to backup/restore dos attributes and creation time over SMB3
   - DFS failover and reconnect fixes
   - Performance optimization for readdir (by using SMB3 compounding)

Buildbot automated functional test results:
     http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com/#/builders/2/builds/312

Note that due to the upcoming SMB3 Test Event (at SNIA SDC next week).
There will likely be more changesets near the end of the merge window
(since we will be testing heavily next week, I held off on some patches
and I expect some additional multichannel patches as well as patches
to enable some additional xfstests).
