KVM: arm64: GICv2: Preserve EOIcount on exit

Browse source

EOIcount is how the virtual CPU interface signals that the guest
is deactivating interrupts outside of the LRs when EOImode==0.

We therefore need to preserve that information so that we can find
out what actually needs deactivating, just like we already do on
GICv3.
