LU-11670 tests: do not fail the first half in sanityn test 103

There are two halves in sanityn test 103. The first half is to
reproduce the problem of incorrect size when using lockahead
and the second half is to verify that the fix works. Sometimes,
the problem cannot be reproduced in the first half test, so we
should not fail the whole test.
