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.
