[gnutls-devel] [PATCH] Don't call _gnutls_cipher_encrypt2 with textlen = 0 in _gnutls_auth_cipher_encrypt2_tag

If the plaintext is shorter than the block size of the used cipher,
_gnutls_auth_cipher_encrypt2_tag calls _gnutls_cipher_encrypt2 with
textlen = 0. By definition _gnutls_cipher_encrypt2 does nothing in this
case and thus does not need to be called.
