Resolve an issue when calling sol_tcp_sockopt() on a socket with ktls
enabled. Prior to this patch, sol_tcp_sockopt() would only allow calls
if the function pointer of setsockopt of the socket was set to
tcp_setsockopt(). However, any socket with ktls enabled would have its
function pointer set to tls_setsockopt(). To resolve this issue, the
patch adds a check of the protocol of the linux socket and allows
bpf_setsockopt() to be called if ktls is initialized on the linux
socket. This ensures that calls to sol_tcp_sockopt() will succeed on
sockets with ktls enabled.
