Fix calculation in move_freepages_block for counting pages

move_freepages_block() returns the number of blocks moved.  This value is used
to determine if a block of pages should be stolen for the exclusive use of a
migrate type or not.  However, the value returned is being used correctly.
This patch fixes the calculation to return the number of base pages that have
been moved.

This should be considered a fix to the patch
move-free-pages-between-lists-on-steal.patch

Credit to Andy Whitcroft for spotting the problem.
