PCI Hotplug: fakephp: fix deadlock... again

Commit fe99740c

 (construct one
fakephp slot per PCI slot) introduced a regression, causing a
deadlock when removing a PCI device.

We also never actually removed the device from the PCI core.

So we:

	- remove the device from the PCI core
	- do not directly call remove_slot() to prevent deadlock

Yu Zhao reported and diagnosed this defect.
