mm/damon/vaddr: protect vma traversal in __damon_va_thre_regions() with rcu read lock
commit fb497d6db7c19c797cbd694b52d1af87c4eebcc6 upstream.
Traversing VMAs of a given maple tree should be protected by rcu read
lock. However, __damon_va_three_regions() is not doing the protection.
Hold the lock.
