iio: frequency: admv1013: fix wrong channel field used in admv1013_read_raw()

Browse source

admv1013_read_raw() switches on chan->channel instead of
chan->channel2 when handling IIO_CHAN_INFO_CALIBBIAS. The channel
field only ever holds 0 or 1 (see ADMV1013_CHAN_CALIB()), while the
IIO_MOD_I / IIO_MOD_Q modifiers are stored in channel2. As a result,
the switch always falls through to the default case and calibbias
reads always fail with -EINVAL, even though the corresponding
admv1013_write_raw() path correctly uses channel2 and works as
expected.

Fix the read path to switch on chan->channel2, matching the write
path and the actual channel_spec definition.
