QemuOpts: Convert qemu_opt_set_number() to Error, fix its use
Return the Error object instead of reporting it with
qerror_report_err().
Change callers that assume the function can't fail to pass
&error_abort, so that should the assumption ever break, it'll break
noisily.
Turns out all callers outside its unit test assume that. We could
drop the Error ** argument, but that would make the interface less
regular, so don't.
