KVM: X86: Fix comments in update_permission_bitmask
The commit 09f037aa48f3 ("KVM: MMU: speedup update_permission_bitmask")
refactored the code of update_permission_bitmask() and change the
comments. It added a condition into a list to match the new code,
so the number/order for conditions in the comments should be updated
too.
