Modified Files:
        src/sys/kern: subr_autoconf.c

Log Message:
Avoid NULL pointer dereference on power handler deregistration if
it was not registered before. I assume that a lot of drivers do not
proper bookkeeping in the case the attach() exits early due to
errors. This is hard to fix and to test, so just be generous here.
