Fix clang warning (reading garbage)

In function `vaCopySurfaceGLX_impl_libva`, if `pSurfaceGLX->gl_context`
points to `struct OpenGLContextState` memory object with all its members
set to 0, the first call of `gl_set_current_context` returns true
without setting the `old_cs`. Then, in the following next call of
`gl_set_current_context`, `&old_cs` will point to random data on the
stack.

Similarly for `vaDestroySurfaceGLX_impl_libva`.
