lib: memcpy_kunit: Fix an invalid format specifier in an assertion msg
[ Upstream commit 0a549ed22c3c7cc6da5c5f5918efd019944489a5 ]
The 'i' passed as an assertion message is a size_t, so should use '%zu',
not '%d'.
This was found by annotating the _MSG() variants of KUnit's assertions
to let gcc validate the format strings.
Fixes: bb95ebbe89a7 ("lib: Introduce CONFIG_MEMCPY_KUNIT_TEST")
