The third parameter of dfu_alt_add(), the string description of alternate, is build in stm32prog_alt_add() with a unnecessary character ';' at the end of the string.

This separator was required in the first implementation of dfu_alt_add() but is no more needed in the current implementation; this separator is managed only in dfu_config_interfaces() which call dfu_alt_add() for this parameter without this separator.

And since the commit 53b406369e9d ("DFU: Check the number of arguments and argument string strictly"), this added character cause an error when the stm32prog command is executed because the third parameter of dfu_alt_add() must be a string with a numerical value; 's' must be NULL in the result of call in dfu_fill_entity_mmc(): third_arg = simple_strtoul(argv[2], &s, 0);
