[PATCH 1/3] net/sfc: move Rx checksum offload check to device level

[Andrew Rybchenko <arybchenko@solarflare.com>]

Rx checksum offloads are on device level and should be checked and
enforced on device level.

Avoid logging of Rx checksum offloads enforced for each Rx queue.

Fixes: ff6a1197c3b1 ("net/sfc: convert to new Rx offload API")
