[PATCH v2 2/3] PCI: use new pci function to get device addition state

[Hari Vyas <hari.vyas@broadcom.com>]

Due to one race condition happening while updating pci
device addition and master status bits in a particular
scenario, device addition state is moved to a independent
private flag variable.

This change uses newly proposed pci_dev_is_added() function
to retrieve device addition state.
