KVM: arm64: nv: Respect exception routing rules for SEAs

Browse source

Synchronous external aborts are taken to EL2 if ELIsInHost() or
HCR_EL2.TEA=1. Rework the SEA injection plumbing to respect the imposed
routing of the guest hypervisor and opportunistically rephrase things to
make their function a bit more obvious.
