s3:smbd/durable: update the low level write_time before disconnecting the file.
If we close the low level FD, we should better update the write_time
if needed.
It's not unlikely that the client doesn't reclaim the durable handle,
in that case we may not close the after the durable timeout.
In such a case we should make sure that we at least update the write time
on disconnect, this makes sure backup applications notice that
the file was changed.
