Aristeu Rozanski 4a466742d2 e752x_edac: Fix pci_dev usage count
commit 90ed4988b8c030d65b41b7d13140e9376dc6ec5a upstream.

In case the device 0, function 1 is not found using pci_get_device(),
pci_scan_single_device() will be used but, differently than
pci_get_device(), it allocates a pci_dev but doesn't does bump the usage
count on the pci_dev and after few module removals and loads the pci_dev
will be freed.
