[ Upstream commit fd0ad3b2365c1c58aa5a761c18efc4817193beb6 ]

Apparently no one noticed that mdp5 plane states leak like a sieve
ever since we introduced plane_state->commit refcount a few years ago
in 21a01abbe32a ("drm/atomic: Fix freeing connector/plane state too
early by tracking commits, v3.")

Fix it by using the right helpers.

Fixes: 21a01abbe32a ("drm/atomic: Fix freeing connector/plane state too early 
by tracking commits, v3.")
