Install an extra hold on the newly allocated synq entry so that it
cannot be freed while do_pass_accept_req is running. This closes a race
where do_pass_establish on another CPU (the driver chose a different
queue for the new tid) expands the synq entry into a full PCB and then
releases the only hold on it, all while do_pass_accept_req is still
running.
