cifs: add cifs_sb_master_tcon and convert some callers to use it
At mount time, we'll always need to create a tcon that will serve as a template for others that are associated with the mount. This tcon is known as the "master" tcon. In some cases, we'll need to use that tcon regardless of who's accessing the mount. Add an accessor function for the master tcon and go ahead and switch the appropriate places to use it.
