ACRN sets the ivposition to the VM_ID in ivshmem_server_bind_peer().
This value should be saved in the ivshmem_device until unbind.
It is wrong to clear ivs_dev->mmio in the ivshmem_vbar_map(),
Instead, it should clear the ivshmem_device structure in the
create_ivshmem_device to ensure the same initial states
after VM reboot case.
