multi-pack-index: refactor "goto usage" pattern

Refactor the "goto usage" pattern added in cd57bc41bbc (builtin/multi-pack-index.c: display usage on unrecognized command, 2021-03-30) and 88617d11f9d (multi-pack-index: fix potential segfault without sub-command, 2021-07-19) to maintain the same brevity, but in a form that doesn't run afoul of the recommendation in CodingGuidelines about braces: When there are multiple arms to a conditional and some of them require braces, enclose even a single line block in braces for consistency[...] Let's also change "argv == 0" to juts "!argv", per: Do not explicitly compare an integral value with constant 0 or '\0', or a pointer value with constant NULL[...] I'm changing this because in a subsequent commit I'll make builtin/commit-graph.c use the same pattern, having the two similarly structured commands match aids readability.
