ASoC: SOF: Intel: cnl: Do not process IPC reply before firmware boot
It is not yet clear, but it is possible to create a firmware so broken
that it will send a reply message before a FW_READY message (it is not
yet clear if FW_READY will arrive later).
Since the reply_data is allocated only after the FW_READY message, this
will lead to a NULL pointer dereference if not filtered out.
The issue was reported with IPC4 firmware but the same condition is present
for IPC3.
