client: move monc->set_want_keys() before monc->init()

if monc's tick connect to the mon before monc.set_want_keys() is called,
monc won't ask for the key for MDS service, and hence will fail to
build_authorizer() for MDS service. this change ready us for the
feature of monc-connect-to-mon-in-parallel.
