    iw_cxgb4: Fix bug 2369 in OFED bugzilla

    Bug 2369 - [OFED-3.5] Trace observed in dmesg while running IMB-MPI1 using
    openmpi-1.6

    dst_neigh_lookup and neigh_release function has been introduced
    in kernel >= 3.4.0. neigh_release function was introduced to
    decrement the reference acquired by dst_neigh_lookup function.
    neigh_release was getting called unnecessary for the kernel < 3.4.0
    which was resulting in the trace.
