Revert QosCallbackException constant values

The constants are used for the NetworkAgent.sendQosCallbackError system
API, so changing their values changes the behavior of that API. This is
observed when running S CTS against the latest version of the
connectivity module: testQosCallbackOnError fails because a
SocketNotConnectedException ends up being reported, instead of an
UnsupportedOperationException.

Revert the constants to their values before change ID:
