inet: fill request sock ir_iif for IPv4
Once request socks will be in ehash table, they will need to have a valid ir_iff field. This is currently true only for IPv6. This patch extends support for IPv4 as well. This means inet_diag_fill_req() can now properly use ir_iif, which is better for IPv6 link locals anyway, as request sockets and established sockets will propagate consistent netlink idiag_if.
