netrom: fix invalid use of sizeof in nr_recvmsg()
[ Upstream commit c802d759623acbd6e1ee9fbdabae89159a513913 ]
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)
