crypto: caam - remove needless ablkcipher key copy
ablkcipher shared descriptors are relatively small, thus there is enough space for the key to be inlined. Accordingly, there is no need to copy the key in ctx->key. Signed-off-by: Horia Geantă <horia.geanta@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
