Pull smb server updates from Steve French:
 "Four ksmbd server fixes, three for stable:

   - Fix an issue where the directory can't be deleted if the share is
     on a file system that does not provide dot and dotdot entries

   - Fix file creation failure if the parent name of pathname is case
     sensitive

   - Fix write failure with FILE_APPEND_DATA flags

   - Add reference count to connection struct to protect UAF of oplocks
     on multichannel"
