rxrpc: Fix checker warnings and errors
Fix various issues detected by checker.
Errors:
(*) rxrpc_discard_prealloc() should be using rcu_assign_pointer to set
call->socket.
Warnings:
(*) rxrpc_service_connection_reaper() should be passing NULL rather than 0 to
trace_rxrpc_conn() as the where argument.
(*) rxrpc_disconnect_client_call() should get its net pointer via the
call->conn rather than call->sock to avoid a warning about accessing
an RCU pointer without protection.
(*) Proc seq start/stop functions need annotation as they pass locks
between the functions.
False positives:
(*) Checker doesn't correctly handle of seq-retry lock context balance in
rxrpc_find_service_conn_rcu().
(*) Checker thinks execution may proceed past the BUG() in
rxrpc_publish_service_conn().
(*) Variable length array warnings from SKCIPHER_REQUEST_ON_STACK() in
rxkad.c.
