[PATCH v4 0/4] Fix some issues from igt runs.

[Maaz Mombasawala <maaz.mombasawala@broadcom.com>]

I ran igt-gpu-tools with vmwgfx and fixed some issues I found.

Changes in v4:
- For ttm ref change, changed to incrementing the refcount on
the ttm base object of the dumb surface instead of holding a
ttm ref object so that it is not exposed to tfile.
- Added Fixes messages.
- Removed BO cleanup patch.

Changes in v3:
- Minor changes so series can apply cleanly on drm-misc-next.

Changes in v2:
- Changes based on Zack's comments.
- For vrefresh changes, removed stdu specific checks so that test
kms_invalid_mode@overflow-vrefresh passes with sou and ldu displays.
For ttm ref changes, fixed a ref leak in ttm_prime_fd_to_handle()
which fixes a memleak in test vmw_prime@tri-map-dmabuf and removed
release callback for dumb buffer surface since the gem buffer will
handle release of the surface.
Added commit to remove duplicate functions in vmwgfx_bo.h.
