char: don't fail when client is not connected
This patch checks that ioc is not null before
using it in tcp socket tcp_chr_add_watch function.
The failure occurs in replay mode of the execution,
when monitor and serial port are tcp servers,
and there are no clients connected to them:
-monitor tcp:127.0.0.1:8081,server,nowait
-serial tcp:127.0.0.1:8082,server,nowait
