Subject: [PATCH 08/10] sysctl: Remove broken cdrom binary sysctls


The binary interface for the cdrom sysctls can't possilby work.
So remove the binary sysctls and update the test for finding
out which sysctl table entry we are dealy with to use the procname
and not the ctl_name (which I am removing).
