kdump/kexec (and of course "ipl") do not reboot on x86, so fixing the
bug does help in making things consistent. :)

Do we really want a reset event for ipl?  Maybe for kexec/kdump, but
perhaps just using SHUTDOWN_CAUSE_NONE for MODIFIED_CLEAR and
LOAD_NORMAL (not sure about the difference) is the way to go.

For example, x86 suspend is a "reboot" but it is already special cased
to use SHUTDOWN_CAUSE_NONE.
