lib/crypto: tests: Fix KMSAN warning in test_sha256_finup_2x()
Fully initialize *ctx, including the buf field which sha256_init()
doesn't initialize, to avoid a KMSAN warning when comparing *ctx to
orig_ctx. This KMSAN warning slipped in while KMSAN was not working
reliably due to a stackdepot bug, which has now been fixed.
Fixes: 6733968be7cb ("lib/crypto: tests: Add tests and benchmark for sha256_finup_2x()")
