iio: core: Fix handling of 'dB'

Browse source 
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: b852822474 ("iio: core: Handle 'dB' suffix in core")
