Set idle timeout to zero when removing fixed channel 

Use Case:
1) pair and Connect to HOGP mouse
2) Disconnect from setting menu.

Failure:
Disconnect is not sent immediately

Root Cause:
While disconnecting we start lcb's default timeout of 4 seconds before
disconnecting the link. Since we are removing fixed channels associated
to a remote, setting idle timeout to 0 for immediate disconnection.
