[BUG] Issues hooking method

I'm trying to hook: https://github.com/aosp-mirror/platform_frameworks_base/blob/26b768d9f86633e4a3c23444b662ae66e4e6ffa4/services/core/java/com/android/server/LocationManagerService.java#L3515

```
private boolean canCallerAccessMockLocation(String opPackageName) {
return mAppOps.checkOp(AppOpsManager.OP_MOCK_LOCATION, Binder.getCallingUid(),
opPackageName) == AppOpsManager.MODE_ALLOWED;
}
```

```
try {
XC_MethodHook.Unhook mockProviderUnhooks;
mockProviderUnhooks = findAndHookMethod("com.android.server.LocationManagerService", classLoader, "canCallerAccessMockLocation", String.class, new XC_MethodReplacement() {
@Override
protected Object replaceHookedMethod(MethodHookParam param) throws Throwable {
//SharedPreferences pref = getPref("preferences");
//if (pref.getBoolean("mockProvider", false)) {
XposedBridge.log("section80 :: canCallerAccessMockLocation");
return true;
//}
}
});

if (mockProviderUnhooks != null) {
XposedBridge.log("section80 :: mock provider hook: " + mockProviderUnhooks.getHookedMethod().getName() + " :: " + mockProviderUnhooks.getHookedMethod().getDeclaringClass().getCanonicalName());
//XposedBridge.log("section80 :: packageName: " + loadPackageParam.packageName + " :: processName: " + loadPackageParam.processName);
}
}
catch (Throwable t) {
XposedBridge.log("section80 :: mock provider hook failed");
}
```

Everything seems to be reporting back fine, xposed supposedly has successfully hooked the method.. however the hook definitely is not working.

It's driving me nuts!

I'm running:
- Android: 10
- Magisk: 20.4 (20400)
- EdXposed: v5.1.4 (4655) SandHook.
- Riru: v23.1

Not sure if I've been staring at this for too long and missing something obvious here, but yeah.. no success.
