drm/vmwgfx: Merge vmw_bo_release and vmw_bo_free functions

[ Upstream commit 37a0cff4551c14aca4cfa6ef3f2f0e0f61d66825 ]

Some of the warnings need to be reordered between these two functions
in order to be correct. This has happened multiple times.
Merging them solves this problem once and for all.
