[PATCH v2 3/4] drm: Move atomic_state_put after locks are dropped

From: Sean Paul <seanpaul at chromium.org>

drm_atomic_state_put doesn't require any locking, and this makes things
easier for switching to modeset_lock_all helpers in a future patch

Changes in v2:
- Moved state->acquire_ctx clear to a separate patch (Daniel)
