Revert c/s 23666:b96f8bdcaa15 KEXEC: disconnect all PCI devices from the PCI bus on crash
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.
