Herbert Xu f688979e42 crypto: api - Add crypto_clone_tfm 
[ Upstream commit 3c3a24cb0ae46c9c45e4ce2272f84f0504831f59 ]

This patch adds the helper crypto_clone_tfm.  The purpose is to
allocate a tfm object with GFP_ATOMIC.  As we cannot sleep, the
object has to be cloned from an existing tfm object.

This allows code paths that cannot otherwise allocate a crypto_tfm
object to do so.  Once a new tfm has been obtained its key could
then be changed without impacting other users.
