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.
