[13/17] qemu: command: Drop QEMU_CAPS_DEVICE for USB

Message ID 908c589705c6a1528d0517c5f698292c34448c3c.1453489952.git.crobinso@redhat.com

Even platforms that don't handle -device well can still use -device
for USB, they will just have a hardcoded USB bus. May still need
extra libvirt changes to make that work, but that's applies to the
current code too.
