media: v4l: fwnode: Fix lane-polarities property parsing

Browse source

fwnode_property_read_u32_array() only returns the number of array elements
if the array argument is NULL. The assumption that it always did so lead to
lane-polarities properties never being read.

Fixes: 4ee236219f ("media: v4l2-fwnode: suppress a warning at OF parsing logic")
