* src/truetype/ttgxvar.c (tt_set_mm_blend): Test `coords`.

It is undefined behavior to pass `NULL` to `memcpy`.  `coords' is
passed to `memcpy` but `TT_Get_MM_Blend` and `TT_Get_Var_Design`
explictly call `tt_set_mm_blend` with `coords` as `NULL`.  In
addition, `TT_Set_MM_Blend` has a similar possible issue.
