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")
