ASoC: SOF: ipc4-topology: Fix an unsigned comparison which can never be negative 

The return value from the call to sof_ipc4_get_valid_bits() is int.
However, the return value is being assigned to an unsigned
int variable 'out_ref_valid_bits', so making it an int.

Eliminate the following warning:
./sound/soc/sof/ipc4-topology.c:1537:6-24: WARNING: Unsigned expression compared with zero: out_ref_valid_bits < 0
