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().
