apps/speed.c: fix ccm performance measurements.

CCM does not support streaming: An additional call to (EVP_...)Update must
precede each call to Update to pass the total message length. The generic
Update_loop calls Update one time such that in case of CCM only the total
message length is passed. No encryption/decryption measured.
