ASoC: tas2781: Use correct calibration data for SINEGAIN2 register

The SINEGAIN2_REG case in cali_reg_update() references t->sin_gn[]
rather than t->sin_gn2[], causing the second pilot tone gain
calibration to be programmed with the wrong register address.

These are distinct fields in struct fct_param_address and are
populated from separate firmware parameters by the parser in
tas2781-fmwlib.c.
