Xie Yongji cddce01160 nbd: Aovid double completion of a request ...

There is a race between iterating over requests in
nbd_clear_que() and completing requests in recv_work(),
which can lead to double completion of a request.

To fix it, flush the recv worker before iterating over
the requests and don't abort the completed request
while iterating.

Fixes: 96d97e1782 ("nbd: clear_sock on netlink disconnect")
