  SVN rev 213711 on 2010-10-11 23:07:12Z by yongari
  
  The IFF_DRV_RUNNING flag is set at the end of bge_init_locked. But
  before setting the flag, interrupt was already enabled such that
  interrupt handler could be run before setting IFF_DRV_RUNNING flag.
  This can lose initial link state change interrupt which in turn
  make bge(4) think that it still does not have valid link. Fix this
  race by protecting the taskqueue with a driver lock.
  While I'm here move reenabling interrupt code after handling of link
  state chage.
