RCX_GET_SLAVE_CONN_INFO_REQ command succeeds if invalid slave handle is used

When scanner is configured, read slave connection information using a not existing handle (see packet below, ulHandle can be upto 0xFFFFFFFE).

Firmware returns the information of the first configured slave.
Expected an error (TLR_E_UNKNOWN_HANDLE?), when handle does not exist in the current configuration.
