inet: introduce dst_rtable() helper
I added dst_rt6_info() in commit
e8dfd42c17fa ("ipv6: introduce dst_rt6_info() helper")
This patch does a similar change for IPv4.
Instead of (struct rtable *)dst casts, we can use :
#define dst_rtable(_ptr) \
container_of_const(_ptr, struct rtable, dst)
Patch is smaller than IPv6 one, because IPv4 has skb_rtable() helper.
