This fixes the following warning from make check. This is triggered
because FSBufferPrefetchUnalignedReads did not clear the callbacks,
and its installe callback can be triggered by other tests.
Add 2 ClearAllCallbacks calls to attempt to avoid these problems.
The callback in TEST_P(PrefetchTest, Basic) did not cause sanitizer
problems, but code inspection shows that I don't think it clears the
callbacks and it probably should.
Fixes:
