net: stmmac: remove unnecessary .pkt_route queue initialisation

PCI drivers explicitly set .pkt_route to zero. However, as the struct
is allocated using devm_kzalloc(), all members default to zero unless
explicitly initialised. Thus, explicitly setting these to zero is
unnecessary. Remove these. This leaves only stmmac_platform.c where
this is explicitly initialised depending on DT properties.

$ grep '\.pkt_route =' *.c
dwmac-intel.c: plat->rx_queues_cfg[0].pkt_route = 0x0;
dwmac-intel.c: plat->rx_queues_cfg[i].pkt_route = 0x0;
