[PATCH] iio: light: veml6070: fix veml6070_read() return value

[Aldo Conte <aldocontelk@gmail.com>]

veml6070_read() computes the sensor value in ret but
returns 0 instead of the actual result. This causes
veml6070_read_raw() to always report 0.

Return the computed value instead of 0.

Running make W=1 returns no errors. I was unable
to test the patch because I do not have the hardware.
Found by code inspection.
