qemu: Unlock monitor when connecting to dest qemu fails

When migrating a qemu domain, we enter the monitor, send some commands,
try to connect to destination qemu, send other commands, end exit the
monitor. However, if we couldn't connect to destination qemu we forgot
to exit the monitor.

Bug introduced by commit d9d518b1c8ef3b65658cc91f85ba33a63c0959a4.
