Fix to return 0 when positive value returned from probe command.
At least --vars can returns a positive value if it found a point. ---- # perf probe --vars vfs_read && echo succeeded! || echo failed! Available variables at vfs_read @<vfs_read+0> char* buf loff_t* pos size_t count struct file* file failed! ----
This fixes above problem. ---- # perf probe --vars vfs_read && echo succeeded! || echo failed! Available variables at vfs_read @<vfs_read+0> char* buf loff_t* pos size_t count struct file* file succeeded! ----
