pppoe/disc: fix init_net allocation size

In init_net(), the buffer for struct disc_net was sized as

    n = _malloc(sizeof(*net) + (HASH_BITS + 1) * sizeof(struct tree));

but 'net' is the const struct ap_net * argument, not the disc_net being
allocated. sizeof(*net) is therefore sizeof(struct ap_net), which is
substantially smaller than sizeof(struct disc_net). Every field of *n
written past the ap_net-sized prefix (ctx, hnd, net, refs, etc.) lands
in unallocated heap memory.

Use sizeof(*n) so the allocation matches the actual destination type.
