efidebug: avoid 'dfu_alt_info not defined' message 

If variable dfu_alt_info is not defined duplicate messages are displayed.

    "dfu_alt_info" env variable not defined!
    Probably dfu_alt_info not defined
    "dfu_alt_info" env variable not defined!
    Probably dfu_alt_info not defined

Remove the 'Probably dfu_alt_info not defined' message.
Instead write a warning if the variable contains no entities.
