ASoC: SOF: trace: only init wait_queue one time

Today we init trace wait_queue at each resume, snd_sof_init_trace_ipc(),
which will clear the wait_queue entry that is waiting for trace update
at suspend, that will lead to sof-logger infinitely waiting for logger
tools like sof-logger so no trace updating or refreshing though we are
back to resume and playback.

Here move this wait_queue initialization to snd_sof_init_trace() which
is called at first boot only, keep waiting trace update during
S0->S3->S0, and fix logger tools no update issues.
