Fixed bug 2833 - Access Violation on SDL_PollEvent after init, delay and quit of joystick subsystem

Jan Klass

Not sure if this is limited to the joystick subsystem,
but I created a minimal program for reproducibility,
which is attached.

The issue occurs with my gamepad Razer Onza (an xbox-style gamepad) plugged in.
On initialization, the gamepad is being recognized.
After quitting the subsystem, the poll will receive the joystick added event,
which it instantly handles itself, calling SDL_SYS_JoystickDetect again,
which this time calls IDirectInput8_EnumDevices with dinput = NULL (after it was released on quit).
This seems to lead to an access violation within said function, which I have no source for.
