rxrpc: Allow list of in-use local UDP endpoints to be viewed in /proc
Allow the list of in-use local UDP endpoints in the current network
namespace to be viewed in /proc.
To aid with this, the endpoint list is converted to an hlist and RCU-safe
manipulation is used so that the list can be read with only the RCU
read lock held.
