svn commit: r285125 - in head/sys: kern sys

[Adrian Chadd]

Heh, well, the sysctl tree changes for me multiple times an hour.

How about we revert this for now and then play around with the better
longer term solution outside of -HEAD? I'm worried that this'll trip
up other developers who load/unload drivers.

Note suspend will also delete sysctl nodes as devices get detached.
It's not just kldunload.
