Yichong Tang 27aee66f88 hv: hyperv: Add hyperv page destory function
In current code process, hyperv data in struct vm_arch is never cleared
during VM shutdown and is retained to next VM launch. As the enabled
bit of hypercall_page msr is not clear, hypercall page might cause fatal
error such as Windows VM BSOD during VM restart and memory
remapping. Hyperv page destory function can ensure hyperv page is
destory during each VM shutdown so hyperv related config such as
hypercall page is established correctly during each VM launch.
