x86, mm: Fix section mismatch in tlb.c

Mark tlb_cpuhp_notify as __cpuinit. It's basically a callback
function, which is called from __cpuinit init_smp_flash(). So -
it's safe.

We were warned by the following warning:

 WARNING: arch/x86/mm/built-in.o(.text+0x356d): Section mismatch
 in reference from the function tlb_cpuhp_notify() to the
 function .cpuinit.text:calculate_tlb_offset()
 The function tlb_cpuhp_notify() references
 the function __cpuinit calculate_tlb_offset().
 This is often because tlb_cpuhp_notify lacks a __cpuinit
 annotation or the annotation of calculate_tlb_offset is wrong.
