Fixed bug #638

 Philipp Nordhus      2008-11-05 13:56:33 PST

The Linux version of SDL_SYS_JoystickQuit() tries to free an invalid pointer
when the number of joysticks was reduced since the last call.

Reproduce: Connect two joysticks, call SDL_Init() and SDL_Quit(), then
disconnect one joystick and call the functions again.
