ext4: Use EXT4_GROUP_INFO_NEED_INIT_BIT during resize
The new groups added during resize are flagged as need_init group. Make sure we properly initialize these groups. When we have block size < page size and we are adding new groups the page may still be marked uptodate even though we haven't initialized the group. While forcing the init of buddy cache we need to make sure other groups part of the same page of buddy cache is not using the cache. group_info->alloc_sem is added to ensure the same.
