iommu/amd: Reevaluate vector configuration on activate()

With the upcoming reservation/management scheme, early activation will
assign a special vector. The final activation at request_irq() assigns a
real vector, which needs to be updated in the tables.

Split out the reconfiguration code in set_affinity and use it for
reactivation.
