[Mesa-dev] [PATCH 17/30] i965: Finalize miptrees before prepare_texture

[Jason Ekstrand]

In order to do resolves for texture views with different formats, we
need intel_texture_object::_Format to be valid.  Calling
intel_finalize_mipmap_tree can safely be done multiple times in a row
and should be a fairly cheap operation.
