crypto: hash - Fix async import on shash algorithm
The function shash_async_import did not initialise the descriptor correctly prior to calling the underlying shash import function. This patch adds the required initialisation. Reported-by: Miloslav Trmac <mitr@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
