Audio: EQIIR: Fix in IPC4 invalid coefficients blob set at init()

The cfg->size is the size of ipc4_base_module_cfg. The
cfg->data is NULL but when such is encountered the
comp_init_data_blob() allocates a zero bytes of size.

Such blob is illegal and e.g. IIR will fail if not another
blob is received by prepare(). DC block operates,
but applies a rather high cut-off frequency that results
to silent audio for e.g. lower voice frequencies. What
happens with such illegal blob is component specific.

The expected operation for most components is pass-through
when a configuration blob is not set. This change should
ensure that the component is not initialized with incorrect
bytes control data if such is not passed with topology.
