ipmi: make sure drivers were registered before unregistering them
The ipmi code will never register a PCI or Open Firmware driver if a
hardcoded device is provided by the user by providing device addresses via
the module parameters. This can cause us to attempt to unregister a
driver that was never registered, resulting in an oops. Keep track of
registration in order to avoid this.
Fixes a post-2.6.34 regression.
