commit bd641fd830 upstream.
We changed these sysfs filenames:
.../pci_bus/<domain:bus>/rescan -> .../pci_bus/<domain:bus>/bus_rescan
.../<domain🚌dev.fn>/rescan -> .../<domain🚌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>".

[bhelgaas: commit log, use __ATTR() both places so we don't have to rename
the attributes]
