Re: [PATCH v6 3/4] net: dropreason: use new __print_sym() in tracing

The __print_symbolic() could only ever print the core
drop reasons, since that's the way the infrastructure
works. Now that we have __print_sym() with all the
advantages mentioned in that commit, convert to that
and get all the drop reasons from all subsystems. As
we already have a list of them, that's really easy.

This is a little bit of .text (~100 bytes in my build)
and saves a lot of .data (~17k).

Thank you for working on that! But it looks like it breaks the
openvswitch test:

https://netdev-ctrl.bots.linux.dev/logview.html?f=%2Flogs%2Fvmksft%2Fnet%2Fresults%2F833743%2F9-openvswitch-sh%2Fstdout#L168

Maybe the test needs to be adapted to get the same info differently?
(and adding CONFIG_TRACEPOINTS to the selftest config file)

Cheers,
Matt
