net: hisilicon: hisi_femac: Stop the receiver before releasing the RX ring
hisi_femac_net_close() frees the receive ring while the RX address queue
still holds every address that was pushed to IQ_ADDR.
A port that keeps receiving then DMAs arrived frames into buffers that
other slab caches have already taken back; on an EC6108V9C (hi3798mv100)
the queue still held all 52 armed addresses right after the interface
was closed, and had dropped to 43 after 15 s of broadcast traffic.
Reset the port before the buffers are released, so that the receiver no
longer holds any of their addresses.
