netrom: fix invalid use of sizeof in nr_recvmsg()
sizeof() when applied to a pointer typed expression gives the size of the pointer, not that of the pointed data. Introduced by commit 3ce5ef(netrom: fix info leak via msg_name in nr_recvmsg) Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: David S. Miller <davem@davemloft.net>
