xfree86: xv: set pointers to NULL in xf86XVFreeAdaptor
As a good practice and for eventual double frees. The reason of this patch is due the resilience of xf86XVInitAdaptors, where for any adaptor failure it's able to keep trying registering the following ones. I discussed briefly with Pauli and Ville about a bigger refactoring of such function, doing it in a way to return instantly when a failure happens; after all that's how mostly of the other driver functions work. Instead, we just thought that xf86XVInitAdaptors is wise and cool, and eventually other driver functions should be even following the main idea of resilience.
