Colin Ian King 288320f6e9 iio: tsl2x7x/tsl2772: avoid potential division by zero
It may be possible for tsl2772_get_lux to return a zero lux value
and hence a division by zero can occur when lux_val is zero. Check
for this case and return -ERANGE to avoid the division by zero.

Detected by CoverityScan, CID#1469484 ("Division or modulo by zero")
