amd64: a simplication to pmap_remove_{all,write}

Eliminate some unnecessary unlocking and relocking when we have to retry
the operation to avoid deadlock.  (All of the other pmap functions that
iterate over a PV list already implemented retries without these same
unlocking and relocking operations.)
