Subject: [PATCH AUTOSEL 5.9 11/33] kunit: fix display of failed expectations for strings

From: Daniel Latypov <dlatypov@...gle.com>

[ Upstream commit 3084db0e0d5076cd48408274ab0911cd3ccdae88 ]

Currently the following expectation
  KUNIT_EXPECT_STREQ(test, "hi", "bye");
will produce:
  Expected "hi" == "bye", but
      "hi" == 1625079497
      "bye" == 1625079500

After this patch:
  Expected "hi" == "bye", but
      "hi" == hi
      "bye" == bye

KUNIT_INIT_BINARY_STR_ASSERT_STRUCT() was written but just mistakenly
not actually used by KUNIT_EXPECT_STREQ() and friends.
