P11KeyPairGenerator throws ProviderException instead of InvalidParameterException with unsupported keysize

In 6u, the bug fix JDK-8072452 increased DH/DSA keysize limits.

From regression test (sun.security.pkcs11.KeyPairGenerator.TestDH2048) with SunPKCS11-NSS
        KeyPairGenerator kpg = KeyPairGenerator.getInstance("DH", p);
        kpg.initialize(3072);//not supported with nss version 3.13
        KeyPair kp1 = kpg.generateKeyPair();


In this case (when tested with unsupported keysize) the sun/security/pkcs11/P11KeyPairGenerator.java throws java.security.ProviderException instead if IPE:

The 7u-cpu build jdk1.7.0_171b06 gives InvalidParameterException as expected when checked with higher unsupported keysize.
