i2c/tsl2550: Fix lux value in dark environment
commit 96f699ad09c8b3c55cd229506a9add0047838e3e upstream.
I've tested TSL2550 driver and I've found a bug: when light is off,
returned value from tsl2550_calculate_lux function is -1 when it should
be 0 (sensor correctly read that light was off).
I think the bug is that a zero c0 value (approximated value of ch0) is
misinterpreted as an error.
