Register sysctl before doing pci registration.

Browse Source 
This fixes a bug when renaming multiple wireless cards on slow devices.
The pci registration causes udev to rename the device but the sysctl is
not registered yet so the device renames but the corresponding sysctl
entries are not renamed.
