x86: don't define __this_fixmap_does_not_exist()
Impact: improve out-of-range fixmap index debugging Commit "1b42f51630c7eebce6fb780b480731eb81afd325" defined the __this_fixmap_does_not_exist() function with a WARN_ON(1) in it. This causes the linker to not report an error when __this_fixmap_does_not_exist() is called with a non-constant parameter. Ingo defined __this_fixmap_does_not_exist() because he wanted to get virt addresses of fix memory of nest level by non-constant index. But we can fix this and still keep the link-time check: We can get the four slot virt addresses on link time and store them to array slot_virt[]. Then we can then refer the slot_virt with non-constant index, in the ioremap-leak detection code.
