include: never overwrite realInputProc with enqueueInputProc. Bug #13511

Browse source 
In some cases (triggered by a key repeat during a sync grab) XKB unwrapping
can overwrite the device's realInputProc with the enqueueInputProc. When the
grab is released and the events are replayed, we end up in an infinite loop.
Each event is replayed and in replaying pushed to the end of the queue again.

This fix is a hack only. It ensures that the realInputProc is never
overwritten with the enqueueInputProc.

This fixes Bug #13511 (https://bugs.freedesktop.org/show_bug.cgi?id=13511)
