HOGP connection with some HOGP devices were slowed down 

Updating connection parameter with non-zero latency before finishing
HOGP connection causes some HOGP devices reponse slowly during
profile connection. To avoid slowing down the connection, use interop
list to set zero latency for those devices. They can request proper
latency later based on its power state.

Bug: 346692549
Test: m com.android.btservices
Test pairing and reconnecting HOGP devices(Mad mouse) and confirm
the connection won't be slow down.
