Remove a fairly useless member of EC_PublicKey that was only used for

handling ImplicitCA ECDSA keys in the CVC code. Currently dealt with
in CVC by simply commenting out the calls - CVC is already pretty
broken and I'd much rather have ECC sane and under control and CVC
totally broken than ECC remaining in its current state.
