[tkreuzer] 48555: [WIN32K] - Remove IntEngExtEscape stub. This function is completely useless. If the driver doesn't provide a DrvEscape, the function should simply fail and must return 0, not -1. - If a NULL surface is passed, pass on NULL pso to the driver function See issue #4563 for more details.

[WIN32K]
- Remove IntEngExtEscape stub. This function is completely useless. If the driver doesn't provide a DrvEscape, the function should simply fail and must return 0, not -1.
- If a NULL surface is passed, pass on NULL pso to the driver function

See issue #4563 for more details.
