HTTP/2: fixed send timer handling.

Checking for return value of c->send_chain() isn't sufficient since there
are data can be left in the SSL buffer.  Now the wew->ready flag is used
instead.

In particular, this fixed a connection leak in cases when all streams were
closed, but there's still some data to be sent in the SSL buffer and the
client forgot about the connection.
