ext4: enable meta_bg only when new desc blocks are needed
This patch addresses an issue observed when resize_inode is disabled
and an online extension of a filesysyem is performed. When a filesystem
is expanded to a size that does not require a addition of a new
descriptor block, the meta_bg feature is being enabled even though no
part of the filesystem uses this layout.
This patch ensures that the meta_bg feature is only enabled if
any of the added block groups utilize meta_bg layout.
