cifs: don't use CREATE_DELETE_ON_CLOSE in cifs_rename_pending_delete
cifs: don't use CREATE_DELETE_ON_CLOSE in cifs_rename_pending_delete
CREATE_DELETE_ON_CLOSE apparently has different semantics than when you
set the DELETE_ON_CLOSE bit after opening the file. Setting it in the
open says "delete this file as soon as this filehandle is closed". That's
not what we want for cifs_rename_pending_delete.
Don't set this bit in the CreateFlags. Experimentation shows that
setting this flag in the SET_FILE_INFO call has no effect.
