ipv6: remove unused function ipv6_skb_idev() 

Commit bdb7cc643f ("ipv6: Count interface receive statistics on the
ingress netdev") removed all callees for ipv6_skb_idev(). Hence, since
then, ipv6_skb_idev() is unused and make CC=clang W=1 warns:

  net/ipv6/exthdrs.c:909:33:
    warning: unused function 'ipv6_skb_idev' [-Wunused-function]

So, remove this unused function and a -Wunused-function warning.
