[PATCH v5 3/8] KVM: arm64: nVHE: Simplify invalid_host_el2_vect

[Pierre-Clément Tosi]

The invalid_host_el2_vect macro is used by EL2{t,h} handlers in nVHE
*host* context, which should never run with a guest context loaded.
Therefore, remove the superfluous vCPU context check and branch
unconditionally to hyp_panic.
