netlink_delinearize: fix decoding of concat data element
Its possible to use update as follows:
meta l4proto tcp update @pinned { ip saddr . ct original proto-src : ip daddr . ct original proto-dst }
... but when listing, only the first element of the concatenation is
shown.
Check if the element size is too small and parse subsequent registers as
well.
