dpdk: pass log-level configuration to EAL

The log-level dpdk config value should be transparently
forwarded to DPDK via EAL argument.  Since DPDK now supports
naming log-levels, VPP no longer needs to parse and call
rte_set_loglevel().

This was the other part of the DPDK log-level change.
It must have got missed during my initial checkin.
Without it passing dynamic log-level values like are silently
ignored.

Fixes: 6ca6ac6c887e ("dpdk: support passing log-level")
