  Log:
  isa_wrongintr() cannot depend on the (void *) unit argument pointing to
  a degenerate structure containing the irq, beacuse isa_wrongintr() is
  called only when the wrong APIC vector is used vs the one we thought we
  programmed.
  
  This commit adjusts isa_wrongintr() to not depend on the unit argument,
  fixing a crash that used to occur in the procedure.  It does not 'fix' the
  interrupt routing bug responsible for causing the entry into isa_wrongintr(),
  which is typically due to broken MP tables.  But at least the problem gets
  reported.  FreeBSD-4.x just locks up without any error message in similar
  situations.
