[PATCH] mm/vmalloc: print correct vmalloc allocation size

[Uladzislau Rezki (Sony)]

On entry the area->nr_pages is not set yet and is zero, thus
when an allocation of the page-table array fails the vmalloc
size will not be reflected correctly in a error message.

Replace area->nr_pages by the nr_small_pages.

Fixes: 014ccf9b888d ("mm/vmalloc: improve allocation failure error messages")
