Pull cifs updates from Steve French:
 "Mostly cleanup, including smb1 refactoring:

   - multichannel perf improvement

   - move additional SMB1 code to not be compiled in when legacy support
     is disabled.

   - bug fixes, including one important one for memory leak

   - various cleanup patches

  We are still working on and testing some deferred close improvements
  including an important lease break fix for case when multiple deferred
  closes are still open, and also some additional perf improvements -
  those are not included here"
