net/handshake: Fix section mismatch in handshake_exit

If CONFIG_NET_NS=n (e.g. m68k/defconfig):

    WARNING: modpost: vmlinux.o: section mismatch in reference: handshake_exit (section: .exit.text) -> handshake_genl_net_ops (section: .init.data)
    ERROR: modpost: Section mismatches detected.

Fix this by dropping the __net_initdata tag from handshake_genl_net_ops.
