perf tools: Fix the bash completion for listing options of perf subcommand
The bash completion does not support listing options for 'perf kvm|kmem|mem|lock|sched --<TAB>', where 'kvm|kmem|mem|lock|sched' are all subcommands of perf. Example: Before this patch: $ perf kvm --<TAB> $ As shown above, the options of perf kvm does not come out. After this patch: $ perf kvm --<TAB> --alloc --caller --input --line --raw-ip --sort --verbose As shown above, the options of perf kvm can come out now.
