mm/z3fold.c: lock z3fold page before __SetPageMovable()
Following zsmalloc.c's example we call trylock_page() and unlock_page().
Also make z3fold_page_migrate() assert that newpage is passed in locked,
as per the documentation.
[akpm@linux-foundation.org: fix trylock_page return value test, per Shakeel]
