Martin Weber c726ceacc1 hw/xfree86: Avoid cursor use after free 
During a VT-Switch a raw pointer to the shared cursor object
is saved which is then freed (in case of low refcount) by a call to
xf86CursorSetCursor with argument pCurs = NullCursor.
This leads to a dangling pointer which can follow in a use after free.

This fix ensures that there is a shared handle saved for the VT-Switch cycle.
