[Qemu-trivial] [PATCH for-1.4 6/6] vl: Exit unsuccessfully on option argument syntax error

[Markus Armbruster]

We exit successfully after reporting syntax error for argument of
--sandbox and --add-fd.

We continue undaunted after reporting it for argument of --option-rom
and --object then.

Change all four to exit unsuccessfully, like the other options.
