Eric Dumazet 907b978e82 net/sched: sch_teql: fix shadowed err in __teql_resolve() 
__teql_resolve() declares an inner 'int err;' inside the
'if (neigh_event_send(n, skb_res) == 0)' block, shadowing the outer
'int err = 0;'. As a result, a negative return from dev_hard_header()
is written to the inner variable and __teql_resolve() still returns 0.

Remove the shadowed variable and set the outer err to -EINVAL when
dev_hard_header() returns a negative error.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
