osu-lazer/osu.Game/Online/API/APIRequestCompletionState.cs
Dean Herbert 80c2b1449b Fix API request potentially firing failed events after completion
Specifically, `Cancel()` calls were not thread safe. Due to a series of
events, `ListPollingComponent` could call `Cancel` from a non-update
thread, leading to a race condition where both a `Success` and `Fail`
event can be fired.

This is intended to be the simplest fix possible, locking and guarding
specifically on the callbacks. Further work could be done in the future
to improve the flow surrounding `pendingFailure`, potentially reducing
redundant work and cleaning up the code, but that's not happening here.

Closes https://github.com/ppy/osu/issues/13632.
