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.
