ksmbd: avoid to send duplicate lease break notifications
This patch fixes generic/011 when enable smb2 leases.
if ksmbd sends multiple notifications for a file, cifs increments
the reference count of the file but it does not decrement the count by
the failure of queue_work.
So even if the file is closed, cifs does not send a SMB2_CLOSE request.
