ext4: teach ext4_mb_init_cache() to skip uptodate buddy caches
After online resize which adds new groups, some of the groups in a buddy page may be initialized and uptodate, while other (new ones) may be uninitialized. The indication for init of new block groups is when ext4_mb_init_cache() is called with an uptodate buddy page. In this case, initialized groups on that buddy page must be skipped when initializing the buddy cache.
