[PATCH] iio: core: Fix handling of 'dB'

[Mircea Caprioru <mircea.caprioru@analog.com>]

This patch fixes the call to iio_str_to_fixpoint when using 'dB' sufix.
Before this the scale_db was not used when parsing the string written to
the attribute and it failed with invalid value.

Fixes: b8528224741b ("iio: core: Handle 'dB' suffix in core")
