rxrpc: Fix misplaced traceline

rxrpc: Fix misplaced traceline

There's a misplaced traceline in rxrpc_input_packet() which is looking at a
packet that just got released rather than the replacement packet.

Fix this by moving the traceline after the assignment that moves the new
packet pointer to the actual packet pointer.
