[dpdk-stable] [PATCH] log: fix level picked with globbing on type register

[Thomas Monjalon]

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")
