hv_balloon: simplify math in alloc_balloon_pages()
'alloc_unit' in alloc_balloon_pages() is either '512' for 2M allocations or
'1' for 4k allocations. So
1 << get_order(alloc_unit << PAGE_SHIFT)
equals to 'alloc_unit' and the for loop basically sets all them offline.
Simplify the math to improve the readability.
