[PATCH net-next 3/4] net: psp: drop psp assoc clear in sk_clone()

[Daniel Zahka]

Unwind the change from commit 1d2929d0850f ("net: psp: do not inherit
the Rx association on clone"), now that assoc state cannot exist on
listen sockets.

With commit 8cc3aef0cb19 ("tcp: Do not allow buggy transitions between
ehash and lhash2."), and the change in this series restricting PSP assoc
operations to established sockets, this state should be unreachable.
