BUG/MEDIUM: mux-h2: Reset padlen when several frames are demux
In the function h2_process_demux(), if several frames are parsed, the padding
length must be reset between each frame. Otherwise we may wrongly think a frame
has a padding block because the previous one was padded.
This patch must be backported to 2.0 and 1.9.
