AudioDeviceInventory: do not clear a2dp/Le suspend on device connection

Only clear the internal LE/A2DP suspend state when a device is
connected but leave external suspend state received from the BT
stack.
This avoids temporarily resetting The suspended state when the A2DP
profile is connected after the HFP profile and SCO audio is already
active.
