Description

cipher: Clear AESWRAP scratch area immediately after use

* cipher/cipher-aeswrap.c (_gcry_cipher_aeswrap_decrypt): Call
wipememory.

Note that gcry_cipher_close will do this also but some applications
keep the context for a long time and thus plaintext could be found in
memory during the time the context is open.
