Subject: [PATCH] Revert "Catch wrong field names length in serde_test"

There are at least two reasonable things to expect the len field to
check: the length of the fields array passed to deserialize_struct, or
the number of field tokens. Even beyond these, in some cases it can be
useful to test deserialization with a bogus len to test how the
Deserialize impl reacts to an incorrect size_hint.

This reverts commit 436cafb0a3f8422cd57ec7760ec406aa85a820b2 which was
released in serde_test 1.0.20.
