[PATCH nft 3/3] tests: fix crash when rule test is malformed

["Pablo M. Bermudo Garay" <pablombg@gmail.com>]

The tests script suffers a crash when a rule test line is malformed
(e.g. if expected result is missing). This commit fixes these crashes
and now the line is skipped and a warning is printed.
