I traced the regression to commit:

commit bc65dcab3bc48673ff6180afb036561a4b8b1119

    radeonsi: avoid syncing the driver thread in si_fence_finish

    It is really only required when we need to flush for deferred fences.

Although I slightly suspect the former code was just making the race condition
much harder to trigger, considering I've played other Dolphin games in the past
(before this regression) and they ocasionally hanged in a similar way after 2-4
hours of continuous play or so (extremely rare to trigger) and it wouldn't
always happen (But that may have been a different bug).
