    vhost/vsock: always initialize vhost_vsock->cpr_paused field
    
    The fields isn't initialized when /dev/vhost-vsock is opened, until
    VHOST_VSOCK_SET_RUNNING ioctl is called.
    
    kvmalloc(..., GFP_KERNEL | __GFP_RETRY_MAYFAIL) does not zero memory.
    Les't make sure the field is always initialized to false on device open.
