Cannot turn off heartbeat from AV server.
Cannot turn off heartbeat from AV server.

The problem is that the server is passing "disable" heartbeat
interval as a constant equal to 7300 days, and this is failing
the range check in Legato.
The fix is to modify the logic in le_avc_SetPollingTimer()
to handle this case properly.
