Check sch_direct_xmit() at the end of sch_direct_xmit() will be bypassed.
"Checking netif_xmit_frozen_or_stopped()", perhaps? Else it doesn't make
much sense...
This is because "ret" from sch_direct_xmit() will be either NETDEV_TX_OK
or NETDEV_TX_BUSY, and only ret == NETDEV_TX_OK == 0 will reach the
condition:
if (ret && netif_xmit_frozen_or_stopped(txq))
return false;
This patch cleans up the code by removing the whole condition.
