tcp: Add a stub for sk_defer_free_flush()
When compiling the kernel with CONFIG_INET disabled, the sk_defer_free_flush() should be defined as a nop. This resolves the following compilation error: ld: net/core/sock.o: in function `sk_defer_free_flush': ./include/net/tcp.h:1378: undefined reference to `__sk_defer_free_flush' Fixes: 79074a72d335 ("net: Flush deferred skb free on socket destroy") Reported-by: kernel test robot <lkp@intel.com> Reviewed-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Gal Pressman <gal@nvidia.com> Reviewed-by: Eric Dumazet <edumazet@google.com> Link: https://lore.kernel.org/r/20220120123440.9088-1-gal@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
