ADI: remove opposite role

In `EngineBase.cpp`, when a role is set for a device, its counterpart
is removed.

However, this is not reflected in the `AudioDeviceInventory` cache.

In this CL, we anticipate that to occur and do the symmetric operation.

Bug: 432772716
Test: m # and verify the roles are updated from the logs
Flag: EXEMPT bug fix
