Some of ctl variables are going to be on the struct
net. Here's the way to adjust the ->data pointer on the
ctl_table-s to point on the right variable.
Since some pointers still point on the global variables,
I keep turning the write bits off on such tables.
This looks to become a common procedure for net sysctls,
so later parts of this code may migrate to some more
generic place.
