Subject: kexec: allow kdump with crash_kexec_post_notifiers
If a crash kernel is loaded, do not crash the running domain. This is
needed if the kernel is loaded with crash_kexec_post_notifiers, because
panic notifiers are run before __crash_kexec() in that case, and this Xen
hook prevents its being called later.
