ALSA: hda/tas2781: do not reset cur_* values in runtime_suspend
The amplifier doesn't loose register state in software shutdown mode, so there is no need to reset the cur_* values. Without these resets, the amplifier can be turned on after runtime_suspend without waiting for the program and profile to be restored.
