SMB3: fix lease break timeout when multiple deferred close handles for the same file.

Solution is to send lease break ack immediately even in case of
deferred close handles to avoid lease break request timing out
and let deferred closed handle gets closed as scheduled.
Later patches could optimize cases where we then close some
of these handles sooner for the cases where lease break is to 'none'
