[Environment]

DPDK version: 24.07.0-rc0
OS: Ubuntu 22.04.3 LTS; 5.15.0-82-generic
Compiler: gcc version 11.4.0
Hardware platform: Intel(R) Xeon(R) Platinum 8280M CPU @ 2.70GHz

[Test Setup]
Steps to reproduce
List the steps to reproduce the issue.

1.Build dpdk
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Denable_kmods=True -Dlibdir=lib  --default-library=static
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc

2.Launch vhost as client mode
x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-3 -n 4  --file-prefix=vhost
--no-pci --vdev 'eth_vhost0,iface=vhost-net,client=1,queues=8'   -- -i
--nb-cores=2 --rxq=2 --txq=2

3, Launch virtio-user as server mode
x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4-6 -n 4  --file-prefix=virtio1
--no-pci --vdev
'net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,server=1,queues=8,mrg_rxbuf=1,in_order=1'
  --single-file-segments -- -i --tx-offloads=0x0 --enable-hw-vlan-strip
--rss-ip --nb-cores=2 --rxq=8 --txq=8

[Actual Result]
Vhost hang's log
