Fixed HIDAPI controller disconnect reading on multiple threads

Browse Source 
If multiple threads are calling SDL_UpdateJoysticks(), then an overlapped read can be initiated on one thread (read_pending set to true) and GetOverlappedResult() called on another thread. This results in ERROR_OPERATION_ABORTED. This is harmless so we shouldn't return an error in this case, we'll just retry the read on the next call.

Fixes https://github.com/libsdl-org/SDL/issues/14033
