Commit b8a926bea8 ("kunit: Introduce KUNIT_EXPECT_MEMEQ and
KUNIT_EXPECT_MEMNEQ macros") introduced a new macro to compare blocks of
memory and, if the test fails, print the result in a human friendly
format. For example, this is the output of a test failure:
Expected res == params->expected, but
res ==
01 02 aa 00 00 00 03 bb 00 <00> 00 04 05
params->expected ==
01 02 aa 00 00 00 03 bb 00 <01> 00 04 05
Use this new macro to replace KUNIT_EXPECT_EQ + memcmp.
