mm: Don't touch uninitialized variable in do_pages_stat_array()

Commit 80bba1290ab5122c60cdb73332b26d288dc8aedd removed one necessary
variable initialization.  As a result following warning happened:

    CC      mm/migrate.o
  mm/migrate.c: In function 'sys_move_pages':
  mm/migrate.c:1001: warning: 'err' may be used uninitialized in this function

More unfortunately, if find_vma() failed, kernel read uninitialized
memory.
