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.
