console: Return EOPNOTSUPP when appropriate
We do not impement most of the mach_notify_* () routines. Explicitly return
an error code so that our caller knows to properly deallocate all resources
the messages may carry.
Even though we don't expect to receive some of the notifications from the kernel
as we never sign up for them, we can always receive spoofed notifications from
our clients, so don't abort in that case.
