ASoC: SOF: sof-client-probes-ipc4: Set param_size extension bits

Write the size of the optional payload of SOF_IPC4_MOD_INIT_INSTANCE
message to extension param_size-bits.

The previous IPC4 version does not set these bits that should indicate
the size of the optional payload (struct sof_ipc4_probe_cfg). The old
firmware side component code works well without these bits, but when
the probes are converted to use the generic module API, this does not
work anymore.

Fixes: ba98c69 (ASoC: SOF: IPC4: probes: Implement IPC4 ops for probes client device)
