Subject: [PATCH] btrfs: abort transaction after failed inode updates in
create_subvol

We can just abort the transaction here, and in fact do that for every other failure in this function except these two cases.

Random context conflicts due to the fs_info cleanup. Fixed up and queued for 4.14-4.4.
