fast-reboot: move pci_reset error handling into fast-reboot code
pci_reset() currently does a platform reboot if it fails. It
should not know about fast-reboot at this level, so instead have
it return an error, and the fast reboot caller will do the
platform reboot.
The code essentially does the same thing, but flexibility is
improved. Ideally the fast reboot code should perform pci_reset
and all such fail-able operations before the CPU resets itself
and destroys its own stack. That's not the case now, but that
should be the goal.
