[Intel-gfx] [PATCH i-g-t] ksm_pipe_color: Set legacy gamma values inside loop.

[Bob Paauwe]

When testing multple outputs, make sure to set the gamma values before
testing the output.  Otherwise we're testing using the gamma values
that were reset after last output was tested.  Without this, the first
output passes, but each output after that will fail.
