dmic: fix pause/release error leading to invalid dmic_active_fifos

The 'in_active' parameter of dmic_stop() is used to control whether
the fifo should be released or not. In case of COMP_TRIGGER_PAUSE,
this should be false and the 'dmic_active_fifos' count should not
be modified.

Without this fix:

  PAUSED -> RELEASE -> dmic_start() -> no change on dmic_active_fifos

  ACTIVE -> PAUSE   -> dmic_stop()  -> dmic_active_fifos--

If a test case repeatedly pauses and releases, 'dmic_active_fifos'
will go out-of-sync.

Fix the issue that dmic_stop for PAUSE does not release the fifo
reference.
