Subject: [net Patch] octeontx2-af: SDP: fix receive link config

On SDP interfaces, frame oversize and undersize errors are
observed as driver is not considering packet sizes of all
subscribers of the link before updating the link config.

This patch fixes the same.

Fixes: 9b7dd87ac071 ("octeontx2-af: Support to modify min/max allowed packet lengths")
