x86: fix section mismatch warning - spp_getpage()
WARNING: vmlinux.o(.text+0x17a3e): Section mismatch in reference from the function set_pte_vaddr_pud() to the function .init.text:spp_getpage() The function set_pte_vaddr_pud() references the function __init spp_getpage(). This is often because set_pte_vaddr_pud lacks a __init annotation or the annotation of spp_getpage is wrong. spp_getpage is called from __init (__init_extra_mapping) and non __init (set_pte_vaddr_pud) functions, so it can't be __init. Unfortunately it calls alloc_bootmem_pages which is __init, but does it only when bootmem allocator is available (after_bootmem == 0). So annotate it accordingly.
