audioreach-driver: q6apm_audio_pkt: remap APM_EVENT_MODULE_TO_CLIENT dest_port

When a GPR response's token isn't found in the audio-packet port map,
module-to-client events (APM_EVENT_MODULE_TO_CLIENT) destined for the
APM module IID were being dropped instead of delivered.

Detect this case and remap the destination port to the SVA client
port (8208), preserving the original source port, so these events
reach the intended client instead of being silently discarded.
