bootmem: clean up alloc_bootmem_core
alloc_bootmem_core has become quite nasty to read over time. This is a
clean rewrite that keeps the semantics.
bdata->last_pos has been dropped.
bdata->last_success has been renamed to hint_idx and it is now an index
relative to the node's range. Since further block searching might start
at this index, it is now set to the end of a succeeded allocation rather
than its beginning.
bdata->last_offset has been renamed to last_end_off to be more clear that
it represents the ending address of the last allocation relative to the
node.
