sysctl: clarify register_sysctl_init() base directory order

Browse Source 
Relatively new docs which I added which hinted the base directories needed
to be created before is wrong, remove that incorrect comment. This has been
hinted before by Eric twice already [0] [1], I had just not verified that
until now. Now that I've verified that updates the docs to relax the context
described.

* init before init levels are processed through proc_sys_init() and
* sysctl_init_bases().
* Context: if your base directory does not exist it will be created for you.
