mkfs: fix parsing of value-less -d/-l concurrency cli option
It's supposed to be possible to specify the -d concurrency option with
no value in order to get mkfs calculate the agcount from the number of
CPUs. Unfortunately I forgot to handle that case (optarg is null) so
mkfs crashes instead. Fix that.
