mesa: Only update enabled VAO gl_vertex_array entries.

Instead of updating all modified gl_vertex_array_object::_VertexArray
entries just update those that are modified and enabled.
Also release buffer object from the _VertexArray that belong
to disabled attributes.

v2: Also set Ptr and Size to zero.
