[PATCH] Change panic_on_oops message to "Fatal exception"

Previously the message was "Fatal exception: panic_on_oops", as introduced
in a recent patch whith removed a somewhat dangerous call to ssleep() in
the panic_on_oops path.  However, Paul Mackerras suggested that this was
somewhat confusing, leadind people to believe that it was panic_on_oops
that was the root cause of the fatal exception.  On his suggestion, this
patch changes the message to simply "Fatal exception".  A suitable oops
message should already have been displayed.
