[PATCH 3.2 005/107] crypto: ixp4xx - Remove bogus BUG_ON on scattered dst buffer

[Ben Hutchings]

3.2.72-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>

commit f898c522f0e9ac9f3177d0762b76e2ab2d2cf9c0 upstream.

This patch removes a bogus BUG_ON in the ablkcipher path that
triggers when the destination buffer is different from the source
buffer and is scattered.
