mesa: optimize no-change check in _mesa_BlendFuncSeparate()
Streamline the checking for no state change in _mesa_BlendFuncSeparate()
(and _mesa_BlendFunc()). If _BlendFuncPerBuffer is false, we only need
to check the 0th buffer state. Move argument validation after the no-op
check.
I'm looking at an app that issues about 1000 redundant glBlendFunc()
calls per frame!
