tests/kms/update: Use proper gamma LUT size

Browse Source 
We're currently pretending the gamma LUT has another size. This becomes
a problem when we try to reset the LUT to passthrough, create an
identity LUT for it and it has a size that the kernel doesn't accept.

We do track the size and have utility for creating the LUTs, so let's
just use them.
