Subject: [PATCH] sysctl: Remove unused ctl_table forward declarations

Remove superfluous forward declarations of ctl_table from header files
where they are no longer needed. These declarations were left behind
after sysctl code refactoring and cleanup.

Apologies for such a big To: list. My idea is for this to go into
mainline through sysctl; get back to me if you prefer otherwise. On the
off chance that this has a V2, let me know if you want to be removed
from the To and I'll make that happen
