vbo: fix missing state validation bugs
Commit 2708ddfb06a36d8568e2aa130bf1f7d551fcd309 caused a few regressions. We need to check/validate state after calling bind_arrays() because it might set the _NEW_ARRAYS flag if the varying VP inputs change. The symptom of this problem was some attribute arrays being ignored (or interpreted as constant-valued) in glDrawRangeElements or glMultiDrawElements. A follow-on patch will add some additional asserts to try to catch this kind of thing in the future. (cherry picked from commit 3cba779e16935f7c3a0bfd8af48bd5e015068e96)
