Log Message:
fix: locking about IFQ_ENQUEUE and ALTQ

- If NET_MPSAFE is not defined, IFQ_LOCK is nop. Currently, that means
  IFQ_ENQUEUE() of some paths such as bridge_enqueue() is called parallel
  wrongly.
- If ALTQ is enabled, Tx processing should call if_transmit() (= IFQ_ENQUEUE
  + ifp->if_start()) instead of ifp->if_transmit() to call ALTQ_ENQUEUE()
  and ALTQ_DEQUEUE().
  Furthermore, ALTQ processing is always required KERNEL_LOCK currently.
