Fixed bug 3939 - Remove static vm_error and vm_event from SDL_x11modes.c

Browse Source

Remove static int vm_error and vm_event, use local variables instead.

This fixes unused variable errors when compiling with SDL_VIDEO_DRIVER_X11_XINERAMA undefined.

src/video/x11/SDL_x11modes.c:505:22: error: unused variable 'vm_error' [-Werror,-Wunused-variable]
