I think 'is_enabled' flag in pci_dev structure should be set/cleared
when the device actually enabled/disabled. Especially about
pci_enable_device(), it can be failed. By this change, we will also
get the possibility of refering 'is_enabled' flag from the functions
called through pci_enable_device()/pci_disable_device().
