if QEMU is configured with modules enabled, it is possible that the
load of an accelerator module will fail.
Abort in this case, relying on module_object_class_by_name to report
the specific load error if any.

I'm not sure aborting is helpful here: QEMU process state is alright,
we only miss a module...

Aren't we good with a simple 'exit(1);'?
