Put `#ifdef notyet' around some code which is currently defunct.

Removed the user area protection gunk I painstakingly removed in revision
...
1.9. It has not been necessary since then due to a segment fixup made to
machdep.c that prevents access to anything above MAX_VMUSER_ADDRESS.

according to andrew, the bit with the comment:

*is* necessary, so put it back in... it's in an #ifdef i386 part anyway.

vm_protect() of the user area is no longer required for i386 machines; the
...
protection is implemented by adjusting the bounds of the user segment
descriptors.

5705dde7e9
Disallow access to the user pages, where the kernel stack is stored. This
...
is effected in useracc(), and also by a vm_protect() in vm_fork() for i386
CPUs. Without the latter a write to the user area, say USRSTACK+1000,
would hang a 386-based system.
