If the allocation of rx_rings fails, the code jumps to\nthe done label leaking both tx_rings and xdp_rings. Furthermore, if\nthe setup of an individual Rx ring fails during the loop, the code jumps\nto the free_tx label which releases tx_rings but leaks xdp_rings.\n\nFix this by introducing a free_xdp label and updating the error paths to\nensure both xdp_rings and tx_rings are properly freed if rx_rings\nallocation or setup fails.\n\nCompile tested only.
