BUG/MEDIUM: h2: Don't forget to wake the tasklet after shutr/shutw.

Browse Source 
When reaching h2_shutr/h2_shutw, as we may have generated an empty frame,
a goaway or a rst, make sure we wake the I/O tasklet, or we may not send
what we just generated.
Also in h2_shutw(), don't forget to return if all went well, we don't want
to subscribe the h2s to wait events.
