Fix bug in SSL bufferevents backed by a bev with a write high-watermarks

Browse Source 
Original mail:

   the logic that handles write watermarks in "bio_bufferevent_write"
   is not working. It currently doesn't write any data if the high
   watermark is *above* the amount of data to write (i.e. when there
   is actually enough room available).
