[PATCH 2/4] block/nbd: correctly use qio_channel_detach_aio_context when needed

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

Don't use nbd_client_detach_aio_context() driver handler where we want
to finalize the connection. We should directly use
qio_channel_detach_aio_context() in such cases. Driver handler may (and
will) contain another things, unrelated to the qio channel.
