41354: workload: don't panic on limiter error r=nvanbenschoten a=nvanbenschoten

`limiter.Wait` can throw the error `Wait(n=1) would exceed context deadline`
if it is asked to wait for longer than a context deadline. This seems to
happen reliably with a workload wait of 2m. There's no reason we need to
turn this into an panic.

Release justification: Testing only.

Release note: None
