Skip event posting for empty slots.
ABS_MT_SLOT comes before any other events. The following order of events
is common for protocol B devices (and mtdev):
...
EV_SYN
ABS_MT_SLOT → posting here means we miss on the position information
ABS_MT_POSITION_X
ABS_MT_POSITION_Y
ABS_MT_SLOT
ABS_MT_POSITION_X
ABS_MT_POSITION_Y
EV_SYN
Store the stot state as SLOT_EMPTY after posting an event (i.e. EV_SYN and
ABS_MT_SLOT) and then don't post until the next slot/syn event.
