Subject: [PATCH net-next 2/2] gianfar: Remove unused field grp_id in gfar_priv_grp

grp_id is obsolete. It has not been used for a long time
now as it has no relevant meaning in the current driver.
Remove it from gfar_priv_grp and put the 'rstat' member
in its place, as rstat needs fast access (and to preserve
consistency of cache line layout according to comments).
