Mesa (master): vbo: Use the VAO array enabled flags in vbo_exec_array.

Module: Mesa
Branch: master
Commit: 43a6f435caf011cc6fd193671ad8eec37dbcb016

vbo: Use the VAO array enabled flags in vbo_exec_array.

Instead of gl_client_array::Enabled inside a VAO,
directly use the gl_vertex_attrib_array::Enabled value
which is the origin of the above.
