Given a zero sk_sndtimeo, llc_ui_connect() skips waiting for state change and returns 0, confusing userspace applications that will assume the socket is connected, making e.g. getpeername() calls error out. More specifically, the issue was discovered in libcoap, where newly-added AF_LLC socket support was behaving differently from AF_INET connections due to EINPROGRESS handling being skipped. Set rc to -EINPROGRESS if connect() would not block, akin to AF_INET sockets.
