[PATCH v2 4/7] PCI: Add device even if driver attach failed

[Rajat Jain]

device_attach() returning failure indicates a driver error while trying to
probe the device. In such a scenario, the PCI device should still be added
in the system and be visible to the user.

This patch partially reverts:
commit ab1a187bba5c ("PCI: Check device_attach() return value always")
