Subject: [PATCH] app/crypto-perf: fix plaintext size exceeds buffer size
When test vector plaintext exceeds buffer size, only the first
max_buffer_size bytes are processed, causing incorrect digest
verification (computed vs expected mismatch).
This patch fixes this issue by checking that the plaintext size is
larger than the buffer size and returns an error with a log.
Fixes: f8be1786b1b8 ("app/crypto-perf: introduce performance test application")
