PCI: sysfs: Revert "rescan" file renames
We changed these sysfs filenames: .../pci_bus/<domain:bus>/rescan -> .../pci_bus/<domain:bus>/bus_rescan .../<domain:bus:dev.fn>/rescan -> .../<domain:bus:dev.fn>/dev_rescan and Ruslan reported [1] that this broke a userspace application. Revert these name changes so both files are named "rescan" again. Note that we have to use __ATTR() to assign custom C symbols, i.e., "struct device_attribute <symbol>".
