[igt-dev] [PATCH i-g-t] Revert "tests/kms_plane: Don't unset primary_fb when testing other planes"

The patch led to a regression in i915 results. The regression wasn't caught pre-merge because the test was blacklisted for pre-merge by yours truly due to its prohibitive execution time, but my creation came back to bite me in the ass, Frakenstein-style. It is currently unclear if the regression introduced by this change is an i915 bug, a KMS spec violation introduced by the change, or generally a loose-spec and just incompatible HW between NVIDIA and Intel. While we figure this thing out, let's just revert the change and put the cost of integration on the people proposing the change (Lyude and I). Sorry for the noise!
