fails early in p9_client_rpc(), req->rc.tag will not be properly initialized. However,
trace_9p_client_res() ends up trying to print it out anyway before p9_client_rpc() finishes. Fix this
issue by assigning default values to p9_fcall fields such as 'tag' and (just in case KMSAN unearths
something new) 'id' during the tag allocation stage. (CVE-2024-39301)
