net neighbour, decnet: Ensure to align device private data on preferred alignment.
To allow both of protocol-specific data and device-specific data attached with neighbour entry, and to eliminate size calculation cost when allocating entry, sizeof protocol-speicic data must be multiple of NEIGH_PRIV_ALIGN. On 64bit archs, sizeof(struct dn_neigh) is multiple of NEIGH_PRIV_ALIGN, but on 32bit archs, it was not. Introduce NEIGH_ENTRY_SPACE() macro to ensure that protocol-specific entry-size meets our requirement.
