s3: smbd: Ensure we set fsp->file_id in openat_pathref_dirfsp_nosymlink().

Browse Source 
This is a subtle one. The dirfsp returned by openat_pathref_dirfsp_nosymlink()
can be used inside open.c and passed to check_parent_access_fsp() to
check if a delete_on_close flag has been set on an existing "real"
open fsp. So the file_id must be correctly set in order for this
to work. Without it, samba3.base.delete fails in deltest20 when
we convert reply_open_and_X() to use filename_convert_dirfsp().
