[dpdk-dev] [PATCH 04/11] kvargs: remove useless size field

[Olivier Matz]

This value was not very useful as the size of the table is fixed (equals
RTE_KVARGS_MAX).

By the way, the memset in the initialization function was wrong (size
too short). Even if it was not really an issue since we rely on the
"count" field, it is now fixed by this patch.
