From: Jakub Kicinski <jakub.kicinski@xxxxxxxxxxxxx> [ Upstream commit b4f47f3848eb70986f75d06112af7b48b7f5f462 ] Unlike '&&' operator, the '&' does not have short-circuit evaluation semantics. IOW both sides of the operator always get evaluated. Fix the wrong operator in tls_is_sk_tx_device_offloaded(), which would lead to out-of-bounds access for for non-full sockets.
