Eric Biggers 9bde9df79f crypto: pcbc - remove bogus memcpy()s with src == dest
commit 251b7aea34ba3c4d4fdfa9447695642eb8b8b098 upstream.

The memcpy()s in the PCBC implementation use walk->iv as both the source
and destination, which has undefined behavior.  These memcpy()'s are
actually unneeded, because walk->iv is already used to hold the previous
plaintext block XOR'd with the previous ciphertext block.  Thus,
walk->iv is already updated to its final value.

So remove the broken and unnecessary memcpy()s.
