[igt-dev] [i-g-t v2 1/6] tests/kms_color: Initialize lut_size before running the test

[Bhanuprakash Modem]

If we try to run the lut_size tests alone, we may get improper
result, b'coz lut_size is not initialized. But in the CI,
igt_runner will run gamma/degamma test first which will cache
the lut_size then run the size tests.

This patch will fix the logic to initialized lut_size before
running any test.
