[igt-dev] [PATCH i-g-t] tests/kms_available_modes_crc: Fix handling of test comparisons

Fixed handling of single plane modes so used bpp never get to
be 0 and ease off crc comparison a bit with gamma tables as
idea of this test is to see chosen modes are able to initialize.

Reduce verboseness if there's no errors.
