Input: ili210x - fix ili251x_read_touch_data() return value
The caller of this function treats all non-zero values as an error, so
the return value of i2c_master_recv() cannot be returned directly.
This fixes touch reporting when there are more than 6 active touches.
Fixes: ef536abd3afd1 ("Input: ili210x - define and use chip operations structure")
