ACPI/PCI: Fix return value of acpi_cuery_osc()
If acpi_query_osc() returns other than AE_OK, __pci_osc_support_set()
stops scanning ACPI objects to evaluate _OSC. This prevents subsequent
_OSCs from being evaluated if some of root bridge doesn't have _OSC, for
example. So acpi_query_osc() should return always AE_OK to evaluate all
_OSC.
