It is enough to just request the data from netlink and skip debugfs when
netlink didn't return an error. The overwrite of the ret variable was only
for testing purposes and should no longer be used.
Fixes: a7bc3d9a2b3f ("alfred: Cache the global translation table entries")

These fixed size packets could have some optional information in the
future. We should therefore not limit the size of these packets to the size
of the non-tlv header.

Any objections? Not sure if this is really necessary. But could be useful
in the future.
