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.
