check if the xDrawable is still registered before freeing it

mutter produces :
Unexpected X error: BadDrawable (invalid Pixmap or Window parameter) serial
14367 error_code 9 request_code 137 minor_code 4)
and abort when resizing a window.

My clue for this patch was that Xserver freed the xDrawable before the client
does. DRI2DrawableGone is indeed called with the same id for the drawable.

Attached patch fix that though it needs review. I am too new to x11 lowlevel
and glx stuff to be confident it is the proper fix. At least it works.
