Merge #12392: Fix ignoring tx data requests when fPauseSend is set on a peer

c4af738 Fix ignoring tx data requests when fPauseSend is set on a peer (Matt Corallo)

Pull request description:

  This resolves a bug introduced in
  66aa1d58a1 where, if when responding
  to a series of transaction requests in a getdata we hit the send
  buffer limit and set fPauseSend, we will skip one transaction per
  call to ProcessGetData.

  Bug found by Cory Fields (@theuni).

  Probably worth slipping into 0.16 :/.
