hal: fix hotword detection failure during music playback

When music playback is started the sound trigger HAL is
informed of capture concurrency to stop detection. This
is happening because the speaker protection is enabled
resulting in vi-feedback capture use case. Fix by ignoring
sending the concurrency event to sound trigger HAL for
this use case.
