x86: early_ioremap_init(), use __fix_to_virt(), because we are sure it's safe
Tetsuo Handa reported this link bug: | arch/x86/mm/built-in.o(.init.text+0x1831): In function `early_ioremap_init': | : undefined reference to `__this_fixmap_does_not_exist' | make: *** [.tmp_vmlinux1] Error 1 Commit:8827247ffcc9e880cbe4705655065cf011265157 used a variable (which would be optimized to constant) as fix_to_virt()'s parameter. It's depended on gcc's optimization and fails on old gcc. (Tetsuo used gcc 3.3) We can use __fix_to_vir() instead, because we know it's safe and don't need link time error reporting.
