Fix PSE PAT handling in guest walk.

Guest walk was currently checking for _PAGE_PSE_PAT flag in
guest_l2e_get_flags(). The problem is that this function only checks
for the first 12 bits of the PDE, while _PAGE_PSE_PAT is actually on bit
12 (that is the 13th bit). This caused _PAGE_PAT bit to never been set on
splintered L1s.
