[ Upstream commit 062fa09f44f4fb3776a23184d5d296b0c8872eb9 ]
When power_up_sst() fails, stream needs to be freed
just like when try_module_get() fails. However, current
code is returning directly and ends up leaking memory.
Fixes: 0121327c1a68b ("ASoC: Intel: mfld-pcm: add control for powering up/down
dsp")
