[PATCH 0/1] MR1772: ntdll: Make sure xmm6-xmm15 are always restored in unix call dispatcher

[Torge Matthies (＠tmatthies)]

If after a unix call `frame->restore_flags` was not 0 but did not include either `CONTEXT_FLOATING_POINT` or `CONTEXT_XSTATE`, xmm6-xmm15 were not restored to their previous values.
