Jiri Olsa 49a5e3edd3 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: 92294b906e ("perf daemon: Dynamically allocate path to perf")
