Same concern is valid for all dynamic log registration but we are ignoring it. What do you think instead of each pmd/lib cover the error case, 'rte_log_register_type_and_pick_level()' & 'rte_log_register()' always return valid value. Like if they fail internally, return 'RTE_LOGTYPE_GENERIC' kind of value.
