RFR: 8367024: JNI exception pending in Java_sun_security_pkcs11_wrapper_PKCS11_C_1DeriveKey of p11_keymgmt.c:950 [v2]

[Koushik Muthukrishnan Thirupattur]

> The method ckAssertReturnValueOK will invoke ckAssertReturnValueOK2 which makes multiple calls to JNI functions, such as FindClass or GetMethodID. These calls would be unsafe as there may be a pending exception at this time.
> So adding exception check to return immediately and do not call any further JNI functions when there is exception pending.
