RFR 8207031 : CKM_SSL3_PRE_MASTER_KEY_GEN used without need in P11RSACipher.class

[Ivan Gerasimov]

Hello!

I was reported that a 3rd-party PKCS11 provider stopped working 
correctly since integrating the fix for JDK-8134605.

This is due to that a secret key is now generated via 
CKM_SSL3_PRE_MASTER_KEY_GEN even if it is going to be discarded 
(presumably, this is to avoid a time-attack.)

Would you please help review a proposed fix:  If the provider fails 
because it does not support CKM_SSL3_PRE_MASTER_KEY_GEN, and we do not 
need the newly generated key, then ignore the failure?
