Input: uinput - fix crash when mixing old and new init style
If user tries to initialize uinput device mixing old and new style
initialization (i.e. using old UI_SET_ABSBIT instead of UI_ABS_SETUP,
we forget to allocate input->absinfo and will crash when trying to send
absolute events:
ioctl(ui, UI_DEV_SETUP, &us);
ioctl(ui, UI_SET_PHYS, "Test");
ioctl(ui, UI_SET_EVBIT, EV_ABS);
ioctl(ui, UI_SET_ABSBIT, ABS_X);
ioctl(ui, UI_SET_ABSBIT, ABS_Y);
ioctl(ui, UI_DEV_CREATE, 0);
