This is not a transaction abort and the filesystem is otherwise ok, so the error should be just propagated to the callers. This is caused by unnecessary call to btrfs_handle_fs_error for all errors, except EAGAIN. This does not make sense as the standard transaction abort mechanism is in btrfs_drop_snapshot so all relevant failures are handled. Originally in commit cb1b69f4508a ("Btrfs: forced readonly when btrfs_drop_snapshot() fails") there was no return value at all, so the btrfs_std_error made some sense but once the error handling and propagation has been implemented we don't need it anymore.
