[PATCH v2 26/38] qemu: Skip USB controller validation when model=none

[Andrea Bolognani via Devel]

This is not useful right now, because the function is simply
not called at all for model=none USB controllers, but that's
going to change in a moment, when we start calling the
function during validation instead of command line generation.
Making this change ahead of time means that we can simply
move the code verbatim later.
