[NTOSKRNL] Remove export version checking for IoConnect/DisconnectInterruptEx()

Since we're going to remove NT6.0+ exports versioning for the kernel soon anyway.
Also, this is badly required by recently imported KMDF stack and the drivers which use it (including the new hdaudbus) to work properly and avoids the failure because of missing exports (for NT5.2 target).
