commit 24e3fce00c0b557491ff596c0682a29dee6fe848 upstream.
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.
Fixes: f9ec5723c3db ("net: ethernet: stmicro: stmmac: move queue reset to dedicated functions")
