[PATCH net v2 1/1] net: stmmac: Add queue reset into stmmac_xdp_open() function

[Song Yoong Siang]

Queue reset was moved out from __init_dma_rx_desc_rings() and
__init_dma_tx_desc_rings() functions. Thus, the driver fails to transmit
and receive packet after XDP prog setup.

This commit adds the missing queue reset into stmmac_xdp_open() function.

v2: Add reviewed-by tag

You don't have to repost to add tags, maintainers will collect 
the tags sent to the list when applying the patch. I'm taking v1.
