PCI: Simplify pci_dev_reset_slot_function()
pci_dev_reset_slot_function() refuses to reset a hotplug slot if it is
shared by multiple pci_devs. That's the case if and only if the slot is
occupied by a multifunction device.
Simplify the function to check the device's multifunction flag instead
of iterating over the devices on the bus. (Iterating over the devices
requires holding pci_bus_sem, which the function erroneously does not
acquire.)
