[PATCH] xf86xvmc: Once hooked into CloseScreen, defer the free after init errors

[Chris Wilson]

After hooking ourselves into the CloseScreen callback, we will attempt
to double-free pAdapt if we free it upon a failure to initialise the
XvMC adaptor and then during CloseScreen. Rather than rearrange the code
to only hook ourselves into CloseScreen, or to disentangle the callback
along a failure path, just defer the free until the end.
