iio: adc: ad4030: don't store scan_type in state

Move getting the scan_type to ad4030_conversion(). Previously, we were
getting the scan_type in two other places, then storing it in the
state struct before using it in ad4030_conversion(). This was a bit
fragile against potential future changes since it isn't obvious that
anything that could potentially change the scan_type would need to
also update the state struct. Also, the non-obviousness of this led to
a redundant call to iio_get_current_scan_type() in
ad4030_single_conversion() since it also calls ad4030_set_mode() which
in turn calls ad4030_conversion().

To simplify things, just call iio_get_current_scan_type() in
ad4030_conversion() where the returned struct is actually used and
don't bother storing it in the state struct.
