KVM: arm64: GICv3: Decouple ICH_HCR_EL2 programming from LRs

Browse source

Not programming ICH_HCR_EL2 while no LRs are populated is a bit
of an issue, as we otherwise don't see any maintenance interrupt
when the guest interacts with the LRs.

Decouple the two and always program the control register, even when
we don't have to touch the LRs.
