Subject: mm/sparse: use MEMBLOCK_ALLOC_ACCESSIBLE enum instead of 0

Setting 'limit' variable to 0 might seem like it means "no limit".  But in
the memblock API, 0 actually means the 'MEMBLOCK_ALLOC_ACCESSIBLE' enum,
which limits the physical address range end based on
'memblock.current_limit'.  This could be confusing.

Use the enum instead of 0 to make it clear.
