OpenSSLCryptoKeyRSA::m_keyType not used?

[Jesse Pelton]

Is OpenSSLCryptoKeyRSA::m_keyType obsolete?  It looks to me like the
only place it is used is in OpenSSLCryptoKeyRSA::clone(), and even there
it is just copied.  Furthermore, it is private, and
OpenSSLCryptoKeyRSA::getKeyType() provides a public (and probably more
robust) way to get the key type based on the contents of the RSA key
member.
