Austin Kim 6da256232c mm/vmalloc.c: move 'area->pages' after if statement 
commit 7ea362427c170061b8822dd41bafaa72b3bcb9ad upstream.

If !area->pages statement is true where memory allocation fails, area is
freed.

In this case 'area->pages = pages' should not executed.  So move
'area->pages = pages' after if statement.

[akpm@linux-foundation.org: give area->pages the same treatment]
