It may happen that DPDK application gets killed while having acquired locks on the ethernet hardware, causing these locks to be never released. On next restart of the application, DPDK skip those ports because it can not acquire the lock, this may cause some ports (or even complete board if SMBI is locked) to be inaccessible from DPDK application until reboot of the hardware.

This patch release locks that are supposed to be locked due to an improper exit of the application.
