inet: use #ifdef CONFIG_SOCK_RX_QUEUE_MAPPING consistently

[ Upstream commit 0cea65f2aa16293afe9f37e433e68cb1e7f3a6a9 ]

Since commit 148a5c47209a ("net/sock: Add kernel config
SOCK_RX_QUEUE_MAPPING"),
sk_rx_queue_mapping access is guarded by CONFIG_SOCK_RX_QUEUE_MAPPING.

Fixes: c9ddda9c1076 ("tcp: Migrate TCP_ESTABLISHED/TCP_SYN_RECV sockets in accept queues.")
