Subject: drm/etnaviv: move object unpinning to submit cleanup
Git-commit: 33a63e68f62bef6981fae781090d480080a73570
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

This is safe to call in all paths, as the BO_PINNED flag tells us if the BO
needs unpinning.
