BUG: payload: fix payload not retrieving arbitrary lengths

This fixes a regression introduced in d7bdcb874bcb, that removed the
ability to use req.payload(0,0) to read the whole buffer content. The
offending commit is present starting in version 1.6, so the patch
should be backported to versions 1.6 and 1.7.
