[RFC PATCH 2/5] drm: Suppress intentional warning backtraces in scaling unit tests

The drm_test_rect_calc_hscale and drm_test_rect_calc_vscale unit tests intentionally trigger warning backtraces by providing bad parameters to the tested functions. What is tested is the return value, not the existence of a warning backtrace. Suppress the backtraces to avoid clogging the kernel log.
