Don't assume buffered output echoes the command.

Browse Source 
The if ((nlptr...)) implicitly assumes commptr != NULL (and that "buf"
starts with "cmd").  Make the assumption explicit, it will be broken in
a future patch.

* src/qemu_driver.c: Don't assume buffered monitor output echoes the
  command.
