Hmm, it shouldn't, unless commit d41f57d15a90 ("brfs: scan but don't register device on single device filesystem") is already in the kernel you are testing.

As we are obliterating the need for the device scan for the single device, which will return success if the basic superblock verification passes, even for the duplicate device of the mounted filesystem, drop the check for the return code in this testcase and continue to verify if the device path of the mounted filesystem remains unaltered after the scan. Also, if the test fails, it leaves the local non-standard mount point remained mounted, leading to further test cases failing. Call unmount in _cleanup().
