====================
net: stmmac: restore previous state if tc_setup_dwmac510_mqprio() fails

Restore previous mqprio qdisc configuration if
tc_setup_dwmac510_mqprio() fails running the following configuration:

  $tc qdisc add dev eth0 root handle 1: mqprio queues 2@0 2@2
  $tc qdisc replace dev eth0 root handle 2: mqprio queues 2@0 2@2 fp E P

Propagate FPE preemption-class mapping errors in
tc_setup_dwmac510_mqprio() and tc_taprio_configure().
