Simplify lifetime management of BDRVNBDState->connection_thread by delaying the possible cleanup of it until the BDRVNBDState itself goes away. This also fixes possible use-after-free in nbd_co_establish_connection when it races with nbd_co_establish_connection_cancel. Signed-off-by: Roman Kagan<rvkagan@yandex-team.ru>
