ASoC: tas2781: Fix calibration issue in stress test 
One specific test condition: the default registers of p[j].reg ~
p[j+3].reg are 0, TASDEVICE_REG(0x00, 0x14, 0x38)(PLT_FLAG_REG),
TASDEVICE_REG(0x00, 0x14, 0x40)(SINEGAIN_REG), and
TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN2_REG). After first calibration,
they are freshed to TASDEVICE_REG(0x00, 0x1a, 0x20), TASDEVICE_REG(0x00,
0x16, 0x58)(PLT_FLAG_REG), TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN_REG),
and TASDEVICE_REG(0x00, 0x16, 0x64)(SINEGAIN2_REG) via "Calibration Start"
kcontrol. In second calibration, the p[j].reg ~ p[j+3].reg have already
become tas2781_cali_start_reg. However, p[j+2].reg, TASDEVICE_REG(0x00,
0x14, 0x44)(SINEGAIN_REG), will be freshed to TASDEVICE_REG(0x00, 0x16,
0x64), which is the third register in the input params of the kcontrol.
This is why only first calibration can work, the second-time, third-time
or more-time calibration always failed without reboot. Of course, if no
p[j].reg is in the list of tas2781_cali_start_reg, this stress test can
work well.
