mesa: call DrawBufferAllocate driver hook in update_framebuffer for windows-system FB
When draw buffers are changed on a bound framebuffer, DrawBufferAllocate()
hook should be called. However, it is missing in update_framebuffer with
window-system framebuffer, in which FB's draw buffer state should match
context state, potentially resulting in a change.
Note: This is needed because gallium delays creating the front buffer,
i965 works fine without this change.
V2 (Timothy Arceri):
- Rebased on merged/simplified DrawBuffer driver function
- Move DrawBuffer call outside fb->ColorDrawBuffer[0] !=
ctx->Color.DrawBuffer[0] check to make piglit pass.
v3 (Timothy Arceri):
- Call new DrawBuffaerAllocate() driver function.
