[PATCH 2/2] command: Move command completion temporary buffer to stack

[Marek Vasut]

The command completion temporary buffer seems to be only
used by the argv tokenizer, move it to stack. This saves
2 kiB from the binary size (depends on configuration) per:
$ aarch64-linux-gnu-readelf -s u-boot | sort -n -k 3
