Jeff Layton c4a2c08db7 cifs: make cnvrtDosUnixTm take a little-endian args and an offset 
The callers primarily end up converting the args from le anyway. Also,
most of the callers end up needing to add an offset to the result. The
exception to these rules is cnvrtDosCifsTm, but there are no callers of
that function, so we might as well remove it.
