drm/plane_helper: Print actual/expected values on failure

Browse source 
Currently the values are printed with debug log level.
Adjust the log level and link the output with the test by using kunit_err.

Example output:
foo: dst: 20x20+10+10, expected: 10x10+0+0
foo: EXPECTATION FAILED at drivers/gpu/drm/tests/drm_plane_helper_test.c:85
