[1/2] net/bnxt: fix freeing aggregation rings

  From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

During port stop, we clear "eth_dev->data->scattered_rx" at the
beginning. As a result, in bnxt_free_hwrm_rx_ring() the check
bnxt_need_agg_ring() returns false and we end up not freeing
the Rx aggregation rings which results in resource leak in the FW.

Fixes: 657c2a7f1dd4 ("net/bnxt: create aggregation rings when needed")
