   drm/i915: Split insertion/binding of an object into the VM

It is useful to have this trace as it pairs nicely with the vma_unbind
one to track vma activity.
Added inside the i915_vma_bind function (was outside before) to keep a
similar placement as trace_i915_vma_unbind.

We need it but that's not the information being used in the bind.
(I know that's what it used to be, but it's a long time since it was
correct.)


would s/flags/bind_flags/ be enough or do you have any other info in mind that you want to pass (e.g. vma->flags)?

Thanks,
Daniele

	ret = vma->vm->bind_vma(vma, cache_level, bind_flags);
	if (ret)
		return ret;
