ALSA: hda/tas2781: do not reset cur_* values in runtime_suspend
[ Upstream commit bec7760a6c5fa59593dac264fa0c628e46815986 ]
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.
