s3:smbd: Align change notify replies on 4-byte boundary
MS-CIFS section 2.2.7.4.2 states this is mandatory. WinXP clients
don't seem to care, but a Win7 client will send an immediate Close()
to the directory handle when receiving an incorrectly aligned
change notify response.
Fix bug #7662 (Change notify replies must be aligned on 4-byte boundary for
Win7.)
