Disable crypto OS helpers on z/OS in FIPS

[farshadasl]

OS helper functions for hardware crypto (GCM and SymmetricCipher) should be disabled in FIPS mode.

In the line

OpenJCEPlus/src/main/java/com/ibm/crypto/plus/provider/base/GCMCipher.java

Line 192 in 8d812f0

Add this:

// The OS_Helper functions are not NIST certified, thus they can't be used in FIPS mode.
if (ockContext.isFIPS()) {
    GCMHardwareFunctionPtr = -1;
}

In the line

OpenJCEPlus/src/main/java/com/ibm/crypto/plus/provider/base/GCMCipher.java

Line 320 in 8d812f0

Add this:

// The OS_Helper functions are not NIST certified, thus they can't be used in FIPS mode.
if (ockContext.isFIPS()) {
    GCMHardwareFunctionPtr = -1;
}

Change the lines 145-151

OpenJCEPlus/src/main/java/com/ibm/crypto/plus/provider/base/SymmetricCipher.java

Line 145 in 8d812f0

if (hardwareEnabled.containsKey(ockContext))

To this:

// The OS_Helper functions are not NIST certified, thus they can't be used in FIPS mode.
if (!ockContext.isFIPS()) {
    if (hardwareEnabled.containsKey(ockContext)) {
        isHardwareSupport = hardwareEnabled.get(ockContext);
    } else {
        hardwareFunctionPtr = checkHardwareSupport(ockContext.getId());
        isHardwareSupport = (hardwareFunctionPtr == 1) ? true : false;
        hardwareEnabled.put(ockContext, isHardwareSupport);
    }
}

@gin-nader, could you please apply the above changes to all branches? Thanks
