BUG: Revert "OPTIM: poll: restore polling after a poll/stop/want sequence"

This reverts commit 12082663561aa2189d243328060c399f2fd95860.

It randomly breaks SSL. What happens is that if the SSL response is
read at once by the SSL stack and is partially delivered to the buffer,
then there's no way to read the next parts because we wait for some
polling first.

So we'll fix this after the polling rework.
