[PATCH] net/ipv6: remove unused err variable on icmpv6_push_pending_frames

[Tim Hansen]

int err is unused by icmpv6_push_pending_frames(), this patch returns removes 
the variable and returns the function with 0.

git bisect shows this variable has been around since linux has been in git in 
commit 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2.  

This was found by running make coccicheck M=net/ipv6/ on linus' tree on commit 
77ede3a014a32746002f7889211f0cecf4803163 (current HEAD as of this patch).
