HID: hid-multitouch: ensure slots are initialized
In case a device does not provide the feature "Maximum Contact Count",
or set it at 0, the maxcontacts field may be at 0 while calling
input_mt_init_slots.
This patch ensures that hid-multitouch will allways report
ABS_MT_SLOT and ABS_MT_TRACKING_ID to the user space.
This corrects a bug found with some Ilitek devices that has been
integrated in 3.0-rc0.
