fix(bitscrambler): clean up loopback create failures

Browse Source 
Clear the returned handle on loopback creation failure and route
initialized objects through bitscrambler_free so channel ownership and
extra cleanup state cannot leak after partial setup errors. Add a
regression test for the failed create path.
