Nikolay Kuratov f924af5294 drm/vmwgfx: Handle surface check failure correctly ...

commit 26498b8d54373d31a621d7dec95c4bd842563b3b upstream.

Currently if condition (!bo and !vmw_kms_srf_ok()) was met
we go to err_out with ret == 0.
err_out dereferences vfb if ret == 0, but in our case vfb is still NULL.

Fix this by assigning sensible error to ret.
