Outside of commit it doesn't make much sense to iterate over the properties.
The only test that enumerates over the array is the reworked kms_atomic, to
see if the value committed is the same as the value returned by getprop.
And the only reason the test does so is because it was easier to store in an
array to memcmp plane->values against kernel_values.
