[PATCH 3/8] ASoC: Intel: avs: Remove redundancy around DAI shutdown

[Cezary Rojewski <cezary.rojewski@xxxxxxxxx>]

Move avs_dai_nonhda_be_shutdown() to avs_dai_shutdown() as the function
is common for all transfer types, not just non-HDAudio ones. Use it
to simplify avs_dai_fe_shutdown().

While at it, fix explicit kfree(data) and use the destructor instead.
