sysctl core: Stop using the unnecessary ctl_table typedef

In sysctl.h the typedef struct ctl_table ctl_table violates coding style isn't
needed and is a bit of a nuisance because it makes it harder to recognize
ctl_table is a type name.

So this patch removes it from the generic sysctl code.  Hopefully I will have
enough energy to send the rest of my patches will follow and to remove it from
the rest of the kernel.
