After 'Machine as QOM' series the machine type input triggers
the creation of the machine class.
If the machine type is set in the configuration file, the machine
class is not updated accordingly and remains the default.

Fixed that by querying the machine options after the configuration
file is loaded.

v1 -> v2:
 - Addressed Paolo Bonzini's comments:
   - moved the call to machine_parse after the switch
     and brought QEMU_OPTION_M near QEMU_OPTION_machine

I sent first the patch only to reviewers and not to the list!
I am sorry about that.
I also didn't actually CC-ed the stable list, doing it now...

Thanks,
Marcel
