[PATCH RFC 6.6] rxrpc: Fix potential UAF after skb_unshare() failure

[Wentao Guan]

Hello, sashal change substituted rxrpc_skb_put_call_rx with rxrpc_skb_put_input
which introduced from commit 9e3cccd176b5e ("rxrpc: Fix CPU time starvation in
I/O thread"). It is hard to clean cherry-pick for 6.6, but possible for v6.12.y?
Maybe the solution is ask for the subsystem maintainer to decide...
