bba2ea17ef libperf tests: If a test fails return non-zero 
If a test fails return -1 rather than 0. This is consistent with the

be82fddca8 libperf tests: Avoid uninitialized variable warning 
The variable 'bf' is read (for a write call) without being initialized
triggering a memory sanitizer warning. Use 'bf' in the read and switch
the write to reading from a string.
