lib/mpi: Remove unused scalar_copied
The scalar_copied variable is not as the scalar is never copied in that block. This patch removes it. Fixes: d58bb7e55a8a ("lib/mpi: Introduce ec implementation to...") Reported-by: Gustavo A. R. Silva <gustavoars@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
