drm/xe: Fix checking for unset value
Commit 37430402618d ("drm/xe: NULL binding implementation") introduced
the NULL binding implementation, but left a case in which the out value
is_vram is not set and the caller will use whatever was on stack.
Eventually the is_vram out could be removed, but this should at least
fix the current bug.
