perf tools: Add missing else to cmd_daemon subcommand condition
Namhyung reported segfault in perf daemon start command.
It's caused by extra check on argv[0] which is set to NULL by previous
__cmd_start call. Adding missing else to skip the extra check.
Fixes: 92294b906e6c ("perf daemon: Dynamically allocate path to perf")
