[Replicant] [libsamsung-ipc] [PATCH 10/14] tools: ipc-modem: Fail if there is no chosen command

Without that fix, if some arguments were set and no
command was given, ipc-modem would proceed anyway:
$ ./tools/ipc-modem --debug
[I] Debug enabled
[...]
As it's expected to at least be used with a command
to do something meaningful, without that fix, it
could misslead users into thinking that everything
is fine when it's not or vice versa.
