examples/fips_validation: remove unused allocation

[ upstream commit 25d392e ]

The val.val pointer is allocated memory, however this memory is then
freed in get_writeback_data() without being used beforehand.
The pointer is then allocated memory again before use,
so the very first allocation is removed as it was unnecessary.
