    bnxt_en: Fix queue start to update vnic RSS table

    HWRM_RING_FREE followed by a HWRM_RING_ALLOC is not guaranteed to
    have the same FW ring ID as before.  So we must reinitialize the
    RSS table with the correct ring IDs.  Otherwise, traffic may not
    resume properly if the restarted ring ID is stale.  Since this
    feature is only supported on P5_PLUS chips, we call
    bnxt_vnic_set_rss_p5() to update the HW RSS table.
