PCI: hotplug: acpiphp: fix slot poweroff problem on systems without _PS3
On systems where the optional _PS3 ACPI object is not implemented acpiphp fails to power off the slot. This is happening because the current code does not attempt to remove power using the _EJ0 ACPI object. This patch restores the _EJ0 evaluation attempt which was apparently inadvertently removed from the power-off sequence when the _EJ0 evaluation code was relocated from power_off_slot() to acpiphp_eject_slot().
