Dandan Bi 631ffb70eb BaseTools/VfrCompile: Add check to avoid using NULL pointer
Question value are stored in one specified storage, but the Data type
of the storage is not specified or there is no sub fields in the Data
type sometimes, so we need to add check before using related pointers.
Here list some NULL cases:
(1)For an efivastore which doesn't specify a data structure or a
   data type(UINT8,UINT16...)as the storage, just has VarName and
   VarSize instead, we can not get its data type before parsing
   its VarSize.

(2)For efivastore which just specifies the data type(UINT8,UINT16...)
   not a structure as the storage,this data type doesn't have sub-fields.
