BUG/MEDIUM: h2: wake the processing task up after demuxing

After the changes to the connection layer in 1.9, some wake up calls
need to be introduced to re-activate reading from the connection. One
such place is at the end of h2_process_demux(), otherwise processing
of input data stops after a few frames.

No backport is needed.
