Subject: [PATCH 2/2] fix qemu-core when vhost-user-net config with server mode

commit 3a223111d7 set default reconnect for vhost-user-net
device, if vhost-user-net config with server mode will
casuse the core when ovs client stop.
tcp_chr_disconnect  --->   set tcp_char state disconnect
tcp_chr start reconnect  ---> set tcp_char state connecting
tcp_char is listen ---> call tcp_chr_accept()
fun tcp_char_accept() set tcp_char state to connecting, but
current tcp_char state already is connecting, assert failed
in tcp_char_change_state() raise qemu core
	assert(s->state == TCP_CHARDEV_STATE_DISCONNECTED)

this commit check tcp_char mode, if tcp_char config with server
mode, dont set reconnect time for tcp_chr.

fix: 3a223111d7 vhost-user: Add support reconnect vhost-user socket
