MINOR: mux-h1: don't try to recv() before the connection is ready
Just as we already do in h1_send(), if the connection is not yet ready,
do not proceed and instead subscribe. This avoids a needless recvfrom()
and subscription to polling for a case which will never work since the
request was not even sent.
