[PATCH AUTOSEL 4.9 17/20] btrfs: abort transaction if we fail to update the delayed inode

[Sasha Levin]

From: Josef Bacik <josef@xxxxxxxxxxxxxx>

[ Upstream commit 04587ad9bef6ce9d510325b4ba9852b6129eebdb ]

If we fail to update the delayed inode we need to abort the transaction,
because we could leave an inode with the improper counts or some other
such corruption behind.
