net: stmmac: remove unnecessary .use_prio queue initialisation

Several drivers (see below) explicitly set the queue .use_prio
configuration to false. However, as this structure is allocated using
devm_kzalloc(), all members default to zero unless otherwise explicitly
initialised. .use_prio isn't, so defaults to false. Remove these
unnecessary initialisations, leaving stmmac_platform.c as the only
file that .use_prio is set true.

$ grep 'use_prio =' *.c
dwmac-intel.c: plat->tx_queues_cfg[0].use_prio = false;
dwmac-intel.c: plat->rx_queues_cfg[0].use_prio = false;
dwmac-intel.c: plat->rx_queues_cfg[i].use_prio = false;
dwmac-intel.c: plat->tx_queues_cfg[i].use_prio = false;
dwmac-loongson.c: plat->tx_queues_cfg[0].use_prio = false;
dwmac-loongson.c: plat->rx_queues_cfg[0].use_prio = false;
stmmac_pci.c: plat->tx_queues_cfg[0].use_prio = false;
stmmac_pci.c: plat->rx_queues_cfg[0].use_prio = false;
stmmac_pci.c: plat->tx_queues_cfg[i].use_prio = false;
stmmac_pci.c: plat->rx_queues_cfg[i].use_prio = false;
stmmac_platform.c: plat->rx_queues_cfg[queue].use_prio = false;
stmmac_platform.c: plat->rx_queues_cfg[queue].use_prio = true;
stmmac_platform.c: plat->tx_queues_cfg[queue].use_prio = false;
stmmac_platform.c: plat->tx_queues_cfg[queue].use_prio = true;
