[PATCH] drm/vmwgfx: Remove unnecessary NULL checks before kvfree()

[Thorsten Blum]

Since kvfree() already checks if its argument is NULL, an additional
check before calling kvfree() is unnecessary and can be removed.

Remove both and the following Coccinelle/coccicheck warnings reported by
ifnullfree.cocci:

  WARNING: NULL check before some freeing functions is not needed
  WARNING: NULL check before some freeing functions is not needed
