__kvm_vcpu_run_vhe() end on VHE with an isb(). However, this
function is only reachable via kvm_call_hyp_ret(), which already
contains an isb() in order to mimick the behaviour of nVHE and
provide a context synchronisation event.
We thus have two isb()s back to back, which is one too many.
Drop the first one and solely rely on the one in the helper.
