soundwire: mipi-disco: add error handling for property array read

The existing code assumes that there are no possible errors when using
fwnode_property_read_u32_array(), because fwnode_property_count_u32()
reads this array to determine its number of elements. We need to also
protect the second read to be completely bullet-proof.
