[POWERPC] Update irq descriptor affinity

Browse source 
The affinity mask in the virq descriptor needs to be set before we
reset the affinity for the virq.  Without doing this the call to get
the new irq server fails and we end up leaving the virq pinned to the
cpu we are removing.

This does not fail the cpu remove from the kernel, but it does prevent
cpu dlpar remove operations from returning the cpu to the hypervisor.
