Leave acpi enabled in panic shutdown case?

[Nate Lawson]

It seems some people may get a 2nd panic when acpi is shutdown after a 
panic.  I think it makes sense not to do the normal shutdown path if 
panicing.  Is the correct way to check for this panicstr != NULL?

The attached patch avoids calling AcpiTerminate() for the panic case.
