net: systemport: fix transmit locking scheme Our transmit locking scheme did not account for the TX ring full interrupt. If a TX ring full interrupt fires while we are attempting to transmit, we will cause a deadlock to occur. Fix this by making sure that we properly disable interrupts while acquiring the spinlock.
