[kvm-unit-tests PATCH] vmx: Fix EPT accessed and dirty flag test

[Cathy Avery <cavery@redhat.com>]

If ept_ad is not supported by the processor or has been
turned off via kvm module param, test_ept_eptp() will
incorrectly leave EPTP_AD_FLAG set in variable eptp
causing the following failures of subsequent
test_vmx_valid_controls calls:

FAIL: Enable-EPT enabled; reserved bits [11:7] 0: vmlaunch succeeds
FAIL: Enable-EPT enabled; reserved bits [63:N] 0: vmlaunch succeeds
