Subject: [PATCH] mbuf: explicit cast of size on detach

[ upstream commit c779ebdca0e4765158bd1eaa6f65c9d714605fae ]

GCC 8.1 warned:

In function 'rte_pktmbuf_detach':
rte_mbuf.h:1580:14: warning: conversion from 'long unsigned int'
to 'uint32_t' {aka 'unsigned int'} may change value [-Wconversion]
  mbuf_size = sizeof(struct rte_mbuf) + priv_size;
              ^~~~~~

Fixes: 355e6735b335 ("mbuf: fix cloning with private mbuf data")
