PCI: fix issue with busses registering multiple times in sysfs
PCI busses can be registered multiple times, so we need to detect if we have registered our bus structure in sysfs already. If so, don't do it again. Thanks to Guennadi Liakhovetski <g.liakhovetski@gmx.de> for reporting the problem, and to Linus for poking me to get me to believe that it was a real problem.
