KVM: MMU: Fix setting the accessed bit on non-speculative sptes
The accessed bit was accidentally turned on in a random flag word, rather than, the spte itself, which was lucky, since it used the non-EPT compatible PT_ACCESSED_MASK. Fix by turning the bit on in the spte and changing it to use the portable accessed mask. Signed-off-by: Avi Kivity <avi@qumranet.com>
