Oliver Upton 17f073f78f KVM: arm64: Correctly identify executable PTEs at stage-2 
KVM invalidates the I-cache before installing an executable PTE on
implementations without DIC. Unfortunately, support for FEAT_XNX
broke this check as KVM_PTE_LEAF_ATTR_HI_S2_XN was expanded to a
bitfield.

Fix it by reusing kvm_pgtable_stage2_pte_prot() and testing the abstract
permission bits instead.

Fixes: 2608563b46 ("KVM: arm64: Add support for FEAT_XNX stage-2 permissions")
