s3/smbd: sticky write time offset miscalculation causes broken timest…

…amps

The offset calculation for the offset that got passed to
fetch_write_time_send() in the enumeration loop was wrong as it passed
the offset before smbd_dirptr_lanman2_entry() added required padding.

This resulted in broken timestamps in the find response.
