Liu Shuo c33e1d5cc6 dm: release host memory after devices de-init 
Devices' de-init process might access some mapped memory space, such as
virtio virtqueues. Access after unmap will cause a fault.

Release the memory map after de-init processes can avoid it. Reading
more code, there are many error handling lost to unmap the memory.
Refined the code to do it.

ACRN Device Model
#################

Introduction
============
The ACRN Device Model provides **device sharing** capabilities between the Service OS and Guest OSs. It is a component that is used in conjunction with the `ACRN Hypervisor`_ and this is installed within the Service OS. You can find out more about Project ACRN on the `Project ACRN documentation`_ website.
