After the switch to reading replies in a coroutine, nothing is reentering pending receive coroutines if the connection hangs. Move nbd_recv_coroutines_enter_all to the reply read coroutine, which is the place where hangups are detected. nbd_teardown_connection can simply wait for the reply read coroutine to detect the hangup and clean up after itself. This wouldn't be enough though because nbd_receive_reply returns 0 (rather than -EPIPE or similar) when reading from a hung connection. Fix the return value check in nbd_read_reply_entry. This fixes qemu-iotests 083.
