alps_process_bitmap was resetting the point bit-count as soon as it saw 2 0 bits in a row. This means that unless the high point actually is at the end of the bitmap, it would always get its num_bits set to 0.
Instead reset num_bits to 0 on a 0-1 transition, so that with > 2 fingers we only count the number of bits occupied by the highest finger.
