kvm tools: fix SMP

We accidently broke SMP when we moved mptable init to before we initialize the vcpu
count, that means that we always built smptable which was not properly initialized
for the given configuration.

Instead of initializing mptable as part of the kvm arch initialization, let it
be initialized on it's own in the firmware initialization level.
