net: rps: move received_rps field to a better location
Commit 14d898f3c1b3 ("dev: Move received_rps counter next
to RPS members in softnet data") was unfortunate:
received_rps is dirtied by a cpu and never read by other
cpus in fast path.
Its presence in the hot RPS cache line (shared by many cpus)
is hurting RPS/RFS performance.
