payload: don't update protocol context if we can't find a description
Since commit
20b1131c07acd2fc ("payload: fix stacked headers protocol context tracking")
we deref null pointer if we can't find a description for the desired
protocol, so "ip protocol 254" crashes while testing protocols 6 or 17
(tcp, udp) works.
Also add a test case for this.
Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1072
