[igt-dev] [PATCH] tests/kms_plane: Fix skips/fails vs CRC cleanup

[Rob Clark <robdclark@gmail.com>]

From: Rob Clark <robdclark@chromium.org>

test_fini() isn't necessarily called if a subtest skips/fails, leaving
the kernel drm_crtc_crc still in the open state, causing further
attempts to open/configure the crc to fail.
