kselftest/arm64: Fail the overall fp-stress test if any test fails

Currently fp-stress does not report a top level test result if it runs to
completion, it always exits with a return code 0. Use the ksft_finished()
helper to ensure that the exit code for the top level program reports a
failure if any of the individual tests has failed.
