[ Upstream commit 9c8921555907f4d723f01ed2d859b66f2d14f08e ]
As the comment of pci_get_domain_bus_and_slot() says, it returns
a PCI device with refcount incremented, so it doesn't need to
call an extra pci_dev_get() in pci_get_dev_wrapper(), and the PCI
device needs to be put in the error path.
Fixes: d4dc89d069aa ("EDAC, i10nm: Add a driver for Intel 10nm server processors")
