dpdk: Stop configuring socket-limit with the value of socket-mem.

Browse Source 
This change removes the automatic memory limit on start-up of OVS with
DPDK. As DPDK supports dynamic memory allocation, there is no
need to limit the amount of memory available, if not requested.

Currently, if socket-limit is not configured, it is set to the value of
socket-mem. With this change, the user can decide to set it or have no
memory limit.

Removed logs that announce this change and fixed documentation.
