ALSA: hda/tas2781: do not reset cur_* values in runtime_suspend

Browse source 
[ Upstream commit bec7760a6c ]

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.
