[CHECKER] 2.4.5-ac4 non-init functions calling init functions

Here are *uninspected* 2.4.5-ac4 results of a checker that warns when a
non-__init function calls an __init function (suggested by
jlundell@lobitos.net). There seem to be two cases:

1. The best case: the caller should actually be an __init function
as well. This is a performance bug since it won't be freed.

2. The worst case: some random post-initialization routine
calls an __init routine which can cause the kernel to go into
hyperspace if the __init routine's code has been deleted.

The current messages do not differentiate between these two cases. If these
results are generally useful, I can fix up the checker, but as it now stands
there shouldn't be that many false positives.
