hv: mod: do not use explicit arch name when including headers Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>". In other words, we are adopting the same practice in Linux kernel.

hv: revert NMI notification by INIT signal NMI is used to notify LAPIC-PT RTVM, to kick its CPU into hypervisor. But NMI could be used by system devices, like PMU (Performance Monitor Unit). So use INIT signal as the partition CPU notification function, to replace injecting NMI. Also remove unused NMI as notification related code.

* If NMI occurs, inject it into current vcpu. Now just PMI is verified.
* For other kind of NMI, it may need to be checked further.
