ASoC: msm: qdsp6: Add error check for memory commands

- Write failures observed during audio playback.
- Error checks are missing for memory map and memory unmap cmds,
  we are proceeding to write data even if memory map is failed. Due
  to this pcm_out_write failures are observed.
- Add proper error handling for memory map and unmap cmds.

ASoC: usb: move the switch setting to more appropriate location

There is a delay between creation of sound card and creating of
corresponding steam. Currently we set the switch at the time of
creation of card. And later streams get created, so its more
optimal if we set the switch only after creating the stream.
