[IPV6] net/ipv6/ndisc.c: remove unused variable
The variable hlen is initialized but never used otherwise. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; identifier i; constant C; @@ ( extern T i; | - T i; <+... when != i - i = C; ...+> ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.
