ar71xx: fix packed-not-aligned error with GCC 8.
Building ar71xx currently fails with:
In file included from ./include/linux/ipv6.h:5,
from ./include/net/ipv6.h:16,
from ./include/net/inetpeer.h:16,
from ./include/net/ip_fib.h:24,
from ./include/net/switchdev.h:17,
from ./include/net/dsa.h:23,
from arch/mips/ath79/dev-dsa.h:15,
from arch/mips/ath79/dev-dsa.c:17:
./include/uapi/linux/ipv6.h:107:1: error: alignment 1 of 'struct ipv6_destopt_hao' is less than 2 [-Werror=packed-not-aligned]
} __attribute__((packed));
Address this issue by correcting the alignment of the struct packing
pragma accordingly.
Fixes: FS#1805
