- 'microvm' and 'q35' machine types already explicitly forbid fallback
- 'isapc' never supported USB and '-usb' is ignored
- 'i440fx' does support '-usb' and translates it into 'piix3-uhci' which
is identical to what libvirt selects
Attempting to start an 'pc' (i440fx) machine with -usb when 'piix3-uhci'
is compiled out will fail and in any other case libvirt will use the
proper explicitly selected controller.
Drop the '-usb' downgrade for x86 arch.
