Do the following fix up in SetupBrowser driver:

1)  Check whether ConfigAccess is NULL before use it.
  2)  Don't do call back for UI_ACTION_REFRESH_FORMSET action.
  3)  Release resource before leave SetupBrowser() function.
  4)  Use the unified check method (HiiHandle, FormsetGuid and FormId) to check FORM is open or close.
