[PATCH v4 24/32] block/nbd: don't touch s->sioc in nbd_teardown_connection()

[Vladimir Sementsov-Ogievskiy]

Negotiation during reconnect is now done in a thread, and s->sioc is
not available during negotiation. Negotiation in thread will be
cancelled by nbd_client_connection_release() called from
nbd_clear_bdrvstate().  So, we don't need this code chunk anymore.
