These macros were hiding that the ops are not zero-initialized by the toolstack. This is needlessly opaque for something so simple, so this patch removes them and replaces them with explicit zero-initialising versions. The patch also removes PHYSDEV_OP from there, as that seems to be an old dead macro.
