rxrpc: Fix some minor issues with bundle tracing
[ Upstream commit 0c3bd086d12d185650d095a906662593ec607bd0 ]
Fix some superficial issues with the tracing of rxrpc_bundle structs,
including:
(1) Set the debug_id when the bundle is allocated rather than when it is
set up so that the "NEW" trace line displays the correct bundle ID.
(2) Show the refcount when emitting the "FREE" traceline.
