The FrameworkHiiOnUefiHiiThunk driver registers notification for creating/adding/removing string/form packages into the UEFI HII Database. The notification handler wants to parse the IFR binary data of the form package. However, the code assumes that a form package have a FORM SET OP and if not, it will assert.  Remove assert and ignore form packages that can not be handled for error tolerant.
