PCI: Make device create/destroy logic symmetric
According to device model documentation, the way to create/destroy PCI devices should be symmetric. The rule is to either use 1) device_register()/device_unregister() or 2) device_initialize()/device_add()/device_del()/put_device(). So change PCI core logic to follow the rule and get rid of the redundant pci_dev_get()/pci_dev_put() pair.
