[PATCH] KVM: arm64: Use cpus_have_final_cap for has_vhe()

[Marc Zyngier]

By the time we start using the has_vhe() helper, we have long
discovered whether we are running VHE or not. It thus makes
sense to use cpus_have_final_cap() instead of cpus_have_const_cap(),
which leads to a small text size reduction.

Thanks, this is really helpful for the 'Split off nVHE code' series. Tested
them together and things seem to work just fine.
