Send the ABS_MT_PRESSURE event in case of untouched with zero pressure. Multitouch pressure is only sent on first touch. Therefore send an ABS_MT_PRESSURE event in case of untouched with zero pressure. This avoids that the next ABS_MT_PRESSURE event will be filtered out by input_defuzz_abs_event() in input.c since the pressure value has not changed.
