When accept failed, we should setup errp with the reason. More importantly, the caller may assume errp be non-NULL when error happens, and not setting the errp may crash QEMU. At the same time, move the trace_qio_channel_socket_accept_fail() after the if check on EINTR. Two reasons: 1. when EINTR happened, it's not really a fault (we should just try again), so we should not log with an "accept failure". 2. trace_*() functions may overwrite errno, then the old errno will be missing. We need to either check errno before trace_*() calls, or reserve the errno.
