Fixed printf format to print 0 correctly

[fliiiix]

Otherwise 0 is printed as 0.

 // works
 printf("Command 0x%02x \n", 0x0);
 
 // broken for 0
 printf("Command %#02x \n", 0x0);
 printf("Command %#02x \n", 0x00);
 printf("Command %#02x \n", 0xFF);

I’d reword the commit message to something less about fixing correctness and more about improving consistency; both 0 and 0x00 are correct. Perhaps something like "Prefix all CDB bytes with 0x, including zeros".

fair enough updated
