Bluetooth: HID: Use proper values of connection status

This patch fixes issue in retrieving correct connection status when
more than one hid device was connected to DUT. In such situation
current implementation was sending STATE_DISCONNECTED as connection
state because of wrong check of matching device as 1st device in
connected device list. Instead of this now actual connection state
device is retrieved from HidService.
