[PATCH] rxrpc: Initialize sockaddr_rxrpc directly

[Matt Jan <zoo868e@gmail.com>]

In rxrpc_lookup_peer_local_rcu(), removed the redundant memset call
that zeros out the sockaddr_rxrpc structure before setting its fields.
Instead, initialize the sockaddr_rxrpc structure directly in
rxrpc_input_error().

This change simplifies the code and ensures that the sockaddr_rxrpc
structure is properly zero-initialized.
