Subject: [PATCH] tests/kms_addfb_basic: avoid excessive logging on legacy
format test
legacy format addfb test try to fuzz kernel with random parameters,
these random parameters cause logging into dmesg. Limit fuzzing
rounds to maximum of 10k (or 1 second) to limit size of created log.
Fixes: https://gitlab.freedesktop.org/drm/intel/-/issues/7017
