ice: reshuffle and group Rx and Tx queue fields by cachelines

Browse source

Place the fields in ice_{rx,tx}_ring used in the same pieces of
hotpath code closer to each other and use
__cacheline_group_{begin,end}_aligned() to isolate the read mostly,
read-write, and cold groups into separate cachelines similarly
to idpf.
