crypto: omap - Avoid redundant copy when using truncated sg list
omap_crypto_cleanup() currently copies data from sg to orig if either
copy flag is set. However OMAP_CRYPTO_SG_COPIED means that sg refers
to the same pages as orig, truncated to len bytes. There is no need
to copy in this case.
Only copy data if the OMAP_CRYPTO_DATA_COPIED flag is set.
