mbuf: fix type of variables in linearize function
GCC 8.1 warned: In function 'rte_pktmbuf_linearize': rte_mbuf.h:1873:32: warning: conversion to 'int' from 'uint32_t' {aka 'unsigned int'} may change the sign of the result [-Wsign-conversion] rte_mbuf.h:2166:13: note: in expansion of macro 'rte_pktmbuf_pkt_len' copy_len = rte_pktmbuf_pkt_len(mbuf) - rte_pktmbuf_data_len(mbuf); rte_mbuf.h:2180:51: warning: conversion to 'size_t' {aka 'long unsigned int'} from 'int' may change the sign of the result [-Wsign-conversion] rte_memcpy(buffer, rte_pktmbuf_mtod(m, char *), seg_len); ^~~~~~~ The temp is consumed as a size_t. So let's make it a size_t in the first place.
