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:
I7102ae9ba7cb9e1cc8d06b252aad4dad75860f3e
Bug: 238061856
Test: cts-tradefed run cts -m CtsNetTestCases \
-t android.net.cts.NetworkAgentTest
using a CTS v12.1 package.
