ACPI/PCI: Always query _OSC control field in pci_osc_control_set()
In current pci_osc_control_set() implementation, once the _OSC control
field is queried, it is never queried again. But the query result can
change depending on the _OSC support field. For example, if PCI Express
Native Hot Plug control depends on ASPM support on a certain platform, a
PCI Express Native Hot Plug Control query would fail before the ASPM
driver was loaded, but it would succeed if the ASPM driver was loaded
first. Therefore, pci_osc_control_set() should query the _OSC control
field every time.
