[PATCH] sysctl: cdrom: don't set de->owner

There is no need for open files in /proc/sys/XXX to hold a reference count on
the module that provides the file to prevent module unload races.  While there
is code active in the module p->used in the sysctl_table_header is
incremented, preventing the sysctl from being unregisted.  Once the sysctl is
unregistered it cannot be found.  Open files are also not a problem as they
revalidate the sysctl information and bump p->used before accessing module
code.

So setting de->owner is unnecessary, makes for a bad example and gets in my
way of removing ctl_table->de.
