x86, nx: Don't force pages RW when setting NX bits

Xen want page table pages read only.

But the initial page table (from head_*.S) live in .data or .bss.

That was broken by 64edc8ed5ffae999d8d413ba006850e9e34166cb.  There is
absolutely no reason to force these pages RW after they have already
been marked RO.
