i965: Use current draw buffer instead of drawable visual to get alpha bits
Use the currently bound draw buffer instead of the visual from the
drawable used to create the context. This cause problems generating
mipmaps for an RGBA texture in an RGB context.
This fixes the failure in piglit's glsl-lod-bias test reported in bug #25614.
