 vmwgfx fixes for regressions in 5.12
 
 Here's a set of 3 patches fixing ugly regressions
 in the vmwgfx driver. We broke lock initialization
 code and ended up using spinlocks before initialization
 breaking lockdep.
 Also there was a bit of a fallout from drm changes
 which made the core validate that unreferenced buffers
 have been unpinned. vmwgfx pinning code predates a lot
 of the core drm and wasn't written to account for those
 semantics. Fortunately changes required to fix it
 are not too intrusive.
 The changes have been validated by our internal ci.
