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.
