Rely on Tethering mutex for TetherInterfaceSM

( cherry-pick of 4bc8d6b1ac0cb7d4192c829a44d988516f0adbdb )

Stop passing Tethering's mutex into TetherInterfaceSM, and instead
simply rely on Tethering to acquire its own mutex when accessing
instances of TetherInterfaceSM.

While here, remove some boolean fields (previously guarded by the mutex)
which duplicate state information.
