Commit 6feb25e833768c41ea7cd6c17f2c61fe362aa4b8 in qpid-dispatch's branch refs/heads/main from Andrew Stitcher

DISPATCH-2298: Avoid rescheduling qd_timer if we are already servicing timer

If we are in the middle of running through the list of timers in
qd_timer_visit() we don't need to wake the timer as anything we add to
the list will get serviced immediately in any case.

> Currently qp_timer_schedule() always calls qd_server_timeout() to wake up the timer callback handler even if the handler is already running. This causes unnecessary system calls in pn_proactor_set_timeout(). If the qp_timer_visit() loop is already running then we are guaranteed that the newly scheduled timer will be noticed by the loop without having to wake the loop up.
