  smb3: improve check for when we send the security descriptor context
on create (2019-12-07 17:38:22 -0600)

----------------------------------------------------------------
9 cifs/smb3 fixes:
      - one fix for stable (oops during oplock break)
      - two timestamp fixes including important one for updating mtime at close
           to avoid stale metadata caching issue on dirty files (also
improves perf
           by using SMB2_CLOSE_FLAG_POSTQUERY_ATTRIB over the wire)
      - two fixes for "modefromsid" mount option for file create
            (now allows mode bits to be set more atomically and
accurately on create
            by adding "sd_context" on create when modefromsid
specified on mount)
       - two fixes for multichannel found in testing this week against
different servers
       - two small cleanup patches
