Restore condition removed in df3747c6607b.

I think it allowed to avoid some TX thread wakeups while the socket
buffer is full.  But add there another options if ic_check_send_space
is set, which means socket just reported that new space appeared, so
it may have sense to pull more data from ic_to_send for better TX
coalescing.
