ADMV1014's get_if_amp_gain() messes up return values

Line 287 in 5f5330d

*i_coarse_gain = no_os_field_get(ADMV1014_IF_AMP_COARSE_GAIN_Q_MSK, data);

shall be changed to:

*q_coarse_gain = no_os_field_get(ADMV1014_IF_AMP_COARSE_GAIN_Q_MSK, data);

to avoid storing q value inside i variable and never returning i value.
