handle device help before accelerator set up

Browse source 
A command line device probe using just -device "?" gets processed
after qemu-kvm initializes the accelerator. If /dev/kvm is not
present, the accelerator check will fail (kvm is defaulted to on),
which causes libvirt to not be set up to handle qemu guests.

Moving the device help handling before the accelerator set up allows
the device probe to work in this configuration and libvirt succeeds
in setting up for a qemu hypervisor mode.
