ipc4: setdx: error checking on core disabling 

If operation of disabling secondary core fails at any of the steps, host
will only learn about it after checking the SPA/CPA bits.

This patch adds checking core state after it disabling. If core will be
still active ipc response will report error.

Additionally, it removes an outdated comment.
