memblock: Use MEMBLOCK_ALLOC_ACCESSIBLE instead of ANYWHERE in memblock_alloc_try_nid()
After node affine allocation fails, memblock_alloc_try_nid() calls
memblock_alloc_base() with @max_addr set to MEMBLOCK_ALLOC_ANYWHERE.
This is inconsistent with memblock_alloc() and what the function's
sole user - sparc/mm/init_64 - expects, although it doesn't make any
difference as sparc64 doesn't have highmem and ACCESSIBLE equals
ANYWHERE.
This patch makes memblock_alloc_try_nid() use ACCESSIBLE instead of
ANYWHERE. This isn't complete as node affine allocation doesn't
consider memblock.current_limit. It will be handled with future
changes.
This patch doesn't introduce any behavior difference.
