ASoC: Intel: Skylake: Avoid freeing up of unallocated memory/mcps 

When DSP pipe/module is not initialized successfully, memory/mcps
is not allocated. So check the pipe/module state to avoid freeing
up of unallocated memory/mcps. And allocate resources when pipe/
module is initialized successfully.
