[PATCH net-next v4 1/9] xen-netback: Introduce TX grant map definitions

This patch contains the new definitions necessary for grant mapping. v2: - move unmapping to separate thread. The NAPI instance has to be scheduled even from thread context, which can cause huge delays - that causes unfortunately bigger struct xenvif - store grant handle after checking validity
