From: Eiichi Tsukata <eiichi.tsukata@xxxxxxxxxxx>
commit ca77fba821351190777b236ce749d7c4d353102e upstream.
Need to call rxrpc_put_peer() for bundle candidate before kfree() as it
holds a ref to rxrpc_peer.
[DH: v2: Changed to abstract out the bundle freeing code into a function]
Fixes: 245500d853e9 ("rxrpc: Rewrite the client connection manager")
