Subject: [PATCH] cxgb4i: Fix neigh entry leak

When csk->atid returned by cxgb4_alloc_atid() is less than zero,
init_act_open() directly returns with -EINVAL. But as init_act_open()
ever invokes dst_neigh_lookup() before it calls cxgb4_alloc_atid(),
this leads to the leak of neigh entry searched by dst_neigh_lookup().
