Avoid 0x80000003 on 32-bit Windows in msnmntr.
The exception occurs in MonitorCoStreamFlowDeletion, but the bug is in MonitorCoCreateFlowContext.
In 32-bit Windows, the high bit of kernel mode pointers is set, and the pointer value is 0x80000000 or above. Casting 0x80000000 to a UINT64 yields 0xffffffff80000000 because of sign extension. ULongLongToULongPtr converts 0xffffffff80000000 to 0xffffffff. Boom.
Cast using an intermediate uintptr_t to avoid the sign extension in the first place.
