uml: more __init annotations
2.6.23-rc1 turned up another batch of references from non-__init code to __init code. In most cases, these were missing __init annotations. In one case (os_drop_memory), the annotation was present but wrong. init_maps is __init, but for some reason was being very careful about the mechanism by which it allocated memory, checking whether it was OK to use kmalloc (at this point in the boot, it definitely isn't) and using either alloc_bootmem_low_pages or kmalloc/vmalloc. So, the kmalloc/vmalloc code is removed.
