[Intel-gfx] [PATCH i-g-t] kms_pipe_color: Don't assert on crc not equal.

[Bob Paauwe]

In this specific case, multiple color values are compared to the
reference with only one expected to have an equal crc. Asserting
on the first case where the crc values aren't equal causes the
various ctm-0-xx-pipex tests to fail.

This reverts

      lib/debugs: nuke igt_crc_equal again

for this test only and makes the igt_crc_equal function a local
function.
