[TCP] Avoid two divides in tcp_output.c
Because 'free_space' variable in __tcp_select_window() is signed, expression (free_space / 2) forces compiler to emit an integer divide. This can be changed to a plain right shift, less expensive. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
