bsp/stm32f10x/touch: return early when lost the position
Check whether finger is still on the screen. If not, we couldn't determine where the user has touched. It's better to return early rather than give garbage values.
A more sensitive solution might be caculate the position once the interrupt occured. But it's not anti-shake friendly.
