SunPKCS11 provider delays the check of DSA key size for SHA1withDSA to sign() instead of init()

When we generate a 2048 bit DSA key, and use it with signature algorithm SHA1withDSA, it is expected that we will catch an InvalidKeyException in the Signature.init(privateKey) method.

But when the test is running on solaris platforn, the expected InvalidKeyException is not thrown, instead, the ProviderException complain about key size out of range is thrown:
java.security.ProviderException: sun.security.pkcs11.wrapper.PKCS11Exception: CKR_KEY_SIZE_RANGE

We should make the behavior consistent.
