bug 1234417 - fix a leak in CreateECPublicKey r=rbarnes Before this patch, CreateECPublicKey would create a SECKEYPublicKey allocated on a scoped arena. It would then call CryptoKey::PublicKeyValid, which has the side-effect of importing the key to the internal PKCS#11 slot. When the arena went out of scope, the memory for the key would be released, but the reference to the slot wouldn't, causing a leak. This patch fixes the leak by making the SECKEYPublicKey a ScopedSECKEYPublicKey (which ensures that the type-specific "destructor" SECKEY_DestroyPublicKey is called, which releases the reference to the PKCS#11 slot).
