x86/paravirt: Remove paravirt ops pmd_update[_defer] and pte_update_defer
pte_update_defer can be removed as it is always set to the same function as pte_update. So any usage of pte_update_defer() can be replaced by pte_update(). pmd_update and pmd_update_defer are always set to paravirt_nop, so they can just be nuked.
