After processing a kvlist in rte_kvargs_process(),
it may be needed to loop again over kvlist in order to know
whether the key is matched or not.
In order to simplify implementation of kvargs checks,
a new pointer parameter may be used to get the match count.
The change of the function prototype would be as below:
int
rte_kvargs_process(const struct rte_kvargs *kvlist,
const char *key_match,
+ int *match_count,
arg_handler_t handler,
void *opaque_arg)

v1: callback for no-match
v2: integer for match count (Olivier suggestion)
