Subject: [PATCH] mesa: update validation when draw buffer changes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Otherwise validation that depends on the _IntegerDrawBuffers and
_FP32DrawBuffers bitfield can end up stale.

Fixes: d04d9da98c9f ("st/mesa: fix _IntegerBuffers bitfield use")
