commit f5fe0adeed6019df495497a64cb57d563ead2296 upstream.
Commit 11e5ea5242e3 ("KVM: arm64: Use helpers to classify exception types reported via ESR") tried to abstract the translation fault check when handling an out-of IPA space condition, but incorrectly replaced it with a permission fault check.
Restore the previous translation fault check.
