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.
