dpdk: Remove default values for socket-mem and limit.
This change removes the default values for EAL args socket-mem and
socket-limit. As DPDK supports dynamic memory allocation, there is no
need to allocate a certain amount of memory on start-up, nor limit the
amount of memory available, if not requested.
Currently, socket-mem has a default value of 1024 when it is not
configured by the user, and socket-limit takes on the value of
socket-mem, 1024, by default. With this change, socket-mem is not
configured by default, meaning that socket-limit is not either.
Neither, either or both options can be set.
Removed extra logs that announce this change and fixed documentation.
