joystick: Fix underflow with 0 delta timestamp

Some sensors will occasionally report two identical timestamps in a row.
This leads to the timestamp wrapping calculation to underflow, subtracting
0x80000000 from the timestamp whenever it happens. By adjusting the wrap
test, we can just directly add zero to the timestamp, fixing the underflow.
