[PATCH] net: dsa: b53: constify xfrm_replay structures

[Julia Lawall]

The xfrm_replay structures are never modified, so declare them as const.

Done with the help of Coccinelle.

You mean b53_io_ops here, right? Other than that LTGM, but this will
have to wait for "net"next to re_open since this is more of a cleanup
than bugfix. Thanks!

net-next is open again, just noticed that, please resubmit with
s/xfrm_read/b53_io_ops/, thanks
