KVM: arm64: Correct test for ICH_HCR_EL2_TDIR cap for GICv5 hosts
The original order of checks in the ICH_HCR_EL2_TDIR test returned
with false early in the case where the native GICv3 CPUIF was not
present. The result was that on GICv5 hosts with legacy support -
which do not have the GICv3 CPUIF - the test always returned false.
Reshuffle the checks such that support for GICv5 legacy is checked
prior to checking for the native GICv3 CPUIF.
