firmware: cs_dsp: add a KUnit test for the cs_dsp_run() error path

Cover the case where the post_run client hook fails: cs_dsp_run() must
return the error and the DSP must not be left marked as running, and a
subsequent run must be able to start it again.

The test fails without the previous patch and passes with it.  Full suite
run (UML, KUnit) on top of that patch:

  before:  Ran 5829 tests: passed: 5825, failed: 4
           (cs_dsp_test_run_error_clears_running in each of the four
            cs_dsp_callbacks_* suites)
  after:   Ran 5829 tests: passed: 5829
