Input: elantench - fix misreporting trackpoint coordinates
commit be896bd3b72b44126c55768f14c22a8729b0992e upstream.
Some firmwares occasionally report bogus data from trackpoint, with X or Y
displacement being too large (outside of [-127, 127] range). Let's drop such
packets so that we do not generate jumps.
