[PATCHSET] Fix regression for a directory dropbox (dir with perm -wx).

[Andreas Schneider]

Hi Jeremy,

with Samba 4.0 we introduced a regression. We are not able to write to a
dropbox (directory with permission -wx, 0733). I've debugged the code and
discussed it with Volker. We came up with the attached patches. We need your
input to this code, please review and comment!

Thanks,
