x86, ept: remove execute permission for granted pages' P2M entries

When backporting c/s 20026 I noticed that granted pages get execute
permission, which doesn't seem desirable (and has been avoided for PV
guests for quite a while).

Even for p2m_mmio_direct is seems suspicious to allow execution, but
me being less certain here I left it as is for the time being.
