[Qemu-devel] [PATCH] vhost: check for vhost_ops before using.

'vhost_set_vring_enable()' tries to call function using pointer to 'vhost_ops' which can be already zeroized in 'vhost_dev_cleanup()' while vhost disconnection. Fix that by checking 'vhost_ops' before using. This fixes QEMU crash on calling 'ethtool -L eth0 combined 2' if vhost disconnected.
