[PATCH v2 03/10] bdev: surface the error from sync_blockdev()

[Christian Brauner <brauner@kernel.org>]

When freeze_super() is called, sync_filesystem() will be called which
calls sync_blockdev() and already surfaces any errors. Do the same for
block devices that aren't owned by a superblock and also for filesystems
that don't call sync_blockdev() internally but implicitly rely on
bdev_freeze() to do it.
