inet: use #ifdef CONFIG_SOCK_RX_QUEUE_MAPPING consistently

Since commit 4e1beecc3b58 ("net/sock: Add kernel config
SOCK_RX_QUEUE_MAPPING"),
sk_rx_queue_mapping access is guarded by CONFIG_SOCK_RX_QUEUE_MAPPING.

Fixes: 54b92e841937 ("tcp: Migrate TCP_ESTABLISHED/TCP_SYN_RECV sockets in accept queues.")
