nbd: close socket if connection breaks
nbd_receive_reply() is called by the event loop whenever data is
available or the socket has been closed by the remote side.
This patch closes the socket when an error occurs to prevent the
nbd_receive_reply() handler from being called indefinitely after the
connection has failed.
Note that we were already correctly returning EIO for pending requests
but leaving the nbd_receive_reply() handler registered resulted in high
CPU consumption and a flood of error messages.
Reuse nbd_teardown_connection() to close the socket.
