[PATCH] ntdll: Only call wine handlers if they're in the same stack.

[Derek Lesho]

In Mortal Kombat 11, the game creates its own stack, with an address higher
than the default wine stack.  Because of this, when we unwind a C++ exception,
we assume we are inside a wine frame, and we crash trying to unwind to it.
