iio: adc: ade9000: fix overlapping scan_index for current and voltage channels

Browse Source 
Current channels used scan_index "num" and voltage "num + 1", so with
phases 0, 1 and 2 the indices overlapped and no longer matched the
IA=0, VA=1, IB=2, VB=3, IC=4, VC=5 layout expected by
ade9000_waveform_buffer_config(). Phase B and C buffers were configured
incorrectly.

Use "num * 2" for current and "num * 2 + 1" for voltage to get the
non-overlapping 0/1, 2/3, 4/5 layout.
