[PATCH net-next v2] net/mlx5e: Fix error handling in RQ memory model registration

[Fushuai Wang <wangfushuai@baidu.com>]

Currently when xdp_rxq_info_reg_mem_model() fails in the XSK path, the
error handling incorrectly jumps to err_destroy_page_pool. While this
may not cause errors, we should make it jump to the correct location.
