rhashtable: reorganize struct rhashtable layout
commit e5d672a0780d9e7118caad4c171ec88b8299398d upstream.
While under frags DDOS I noticed unfortunate false sharing between
@nelems and @params.automatic_shrinking
Move @nelems at the end of struct rhashtable so that first cache line
is shared between all cpus, because almost never dirtied.
