  Register the interrupt handler at the end of wi_attach rather than at
  the beginning.  There's a race in the shared interrutp case.  If
  another interrupt happens after the interrupt is setup, then we'd try
  to lock an uninitialized mutex.  In addition, if we bailed out due to
  a too old version of firmware, we'd leave the interrupt enabled with
  all the fun that ensues....
