Guennadi Liakhovetski 82857a78ba ipc: fix a IPC completion race 
A race currently exists in IPC completion code. When processing the
pipeline TRIG_START command on timer-domain pipelines, processing is
postponed to the pipeline task. Usually the IPC task continues and
completes before the pipeline task. The IPC task notes, that the
command is processed in the pipeline context and doesn't send a
reply to the host. Then the pipeline task executes the command and
notifies the host.

However, occasionally the timer interrupt occurs while the IPC task
is still active. It will start processing the IPC command in the
pipeline context and reply to the host. The host then can send the
next IPC command before the IPC task in the firmware has completed.
This then produces an error trace:

ERROR schedule_edf_task(), task already queued or running 3

and the IPC is dropped.

This commit fixes the race by making sure in asynchronous cases the
last of the two contexts notifies the host.
