[Xen-devel] Revert c/s 23666:b96f8bdcaa15 KEXEC: disconnect all PCI devices from the PCI bus on crash

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

It turns out that this causes all mannor of problems on certain
motherboards (so far with no pattern I can discern)

Problems include:
* Hanging forever checking hlt instruction.
* Panics when trying to change switch root device
* Drivers hanging when trying to check for interrupts.

This changeset needs removing from testing trees as well.
