crypto/openssl: fix CCM processing 0 length source

When given a source length 0 for CCM, the encryption and decryption
functions did not call the EVP_ENCRYPTUPDATE/EVP_DECRYPTUPDATE functions
with a src and dst, causing some FIPS validation failures for testcases
with PLen=0:

process_openssl_auth_encryption_ccm() line 1131:
Process openssl auth encryption ccm failed
