Ian Rogers af515a5587 selftests/xsk: Avoid use-after-free on ctx
The put lowers the reference count to 0 and frees ctx, reading it
afterwards is invalid. Move the put after the uses and determine the
last use by the reference count being 1.

Fixes: 39e940d4ab ("selftests/xsk: Destroy BPF resources only when ctx refcount drops to 0")
