[Qemu-devel] [PATCH RESEND] migration: Fix colo hang in socket_accept_incoming_migration

[Guang Wang]

From: Wang guang <wang.guang55@zte.com.cn>

Due to the feature of accept channel does not support QIO_CHANNEL_FEATURE_SHUTDOWN.
when failover,channel_shutdown could not shut down the channel.
So the colo_process_incoming_thread will hang at recvmsg.
This patch just call qio_channel_socket_new to get channel,
Which set QIO_CHANNEL_FEATURE_SHUTDOWN already.
