[ Upstream commit 1980d37565061ab44bdc2f9e4da477d3b9752e81 ]

(struct tipc_link_info)->dest is in network order (__be32), so we must
convert the value to network order before assigning. The problem detected
by sparse:

net/tipc/netlink_compat.c:699:24: warning: incorrect type in assignment (different base types)
net/tipc/netlink_compat.c:699:24: expected restricted __be32 [usertype] dest
net/tipc/netlink_compat.c:699:24: got int
