cifs: add and use CIFSSMBUnixSetFileInfo for setattr calls
cifs: add and use CIFSSMBUnixSetFileInfo for setattr calls When there's an open filehandle, SET_FILE_INFO is apparently preferred over SET_PATH_INFO. Add a new variant that sets a FILE_UNIX_INFO_BASIC infolevel via SET_FILE_INFO and switch cifs_setattr_unix to use the new call when there's an open filehandle available.
