dpdk: Check other_config:dpdk-extra for '--lcores'.

Browse Source 
Currently dpdk lcore args for DPDK EAL init can be generated or
they can be written directly by the user through dpdk-extra.

If dpdk-extra does not contain '-l' or '-c', a '-l' argument with
a core list for DPDK EAL init will be generated.

The '--lcores' argument should also be checked, as if it is used in
dpdk-extra, currently a '-l' is still generated and that causes
DPDK EAL init to fail:

|00009|dpdk|INFO|EAL ARGS: ovs-vswitchd --lcores 0@18 --in-memory -l 0.
|00012|dpdk|ERR|EAL: Option -l is ignored, because (--lcore) is set!

Add check for '--lcores' in dpdk-extra config and don't generate '-l'
if it is detected:

|00009|dpdk|INFO|EAL ARGS: ovs-vswitchd --lcores 0@8 --in-memory.
