util/execqueue: don't hold mutex in RunSync

2025-11-26T18:09:23Z

We don't hold q.mu while running normal ExecQueue.Add funcs, so we shouldn't in RunSync either. Otherwise code it calls can't shut down the queue, as seen in #18502. Updates #18052 Co-authored-by: Nick Khyl Change-Id: Ic5e53440411eca5e9fabac7f4a68a9f6ef026de1 Signed-off-by: Brad Fitzpatrick
