in the case there are several and the user did not specify one.
This can be useful if the device does not expose its alternate
interfaces in run-time mode, but only in DFU mode.
Also adjusted a warning message to clarify that we do not set
the alternate interface in run-time mode, only in DFU mode.

After looking a bit at this, it seem also that we might need
to clarify the documentation and behaviour on the --configuration,
--interface and --alternate options. In fact we do not support the
--configuration option, however this can be fixed. The --interface
option should not be needed since a DFU device only has one DFU
interface whether in run-time or DFU mode. None of our supported
devices needs this option.
