KVM: arm/arm64: fix the incompatible matching for external abort
kvm_vcpu_dabt_isextabt() tries to match a full fault syndrome, but calls kvm_vcpu_trap_get_fault_type() that only returns the fault class, thus reducing the scope of the check. This doesn't cause any observable bug yet as we end-up matching a closely related syndrome for which we return the same value. Using kvm_vcpu_trap_get_fault() instead fixes it for good.
