When a log type is registered, the level can be picked
by matching saved options.
The check of fnmatch globbing result was reversed.

The same bug was already fixed in a similar function.
This one is acting in log type register function.

Note: this function rte_log_register_type_and_pick_level()
is not used a lot and could be merged with rte_log_register().

Fixes: 6ff0f81d0ef7 ("log: fix pattern matching")

Same fix as a patch I sent quite some time ago and left behind..
https://patchwork.dpdk.org/patch/57742/

I left it in a series I wanted to work on later...
Anyway, this fix is needed.
I suppose we are missing a unit test too.
