CVE-2020-15192: In Tensorflow before versions 2.2.1 and 2.3.1, if a user passes a list of strings to `dlpack.to_dlpack` there is a memor

TensorFlow versions before 2.2.1 and 2.3.1 have a memory leak (wasted computer memory that isn't freed) when users pass a list of strings to a function called `dlpack.to_dlpack`. The bug happens because the code doesn't properly check for error conditions during validation, so it continues running even when it should stop and clean up.
