[PATCH 1/1] X86: mshyperv.c: Fix a compilation issue.

["K. Y. Srinivasan" <kys@microsoft.com>]

Building with a random configuration file, this build failure
was reported:

arch/x86/built-in.o: In function `hv_machine_crash_shutdown':
arch/x86/kernel/cpu/mshyperv.c:112: undefined
reference to `native_machine_crash_shutdown'

This patch fixes the problem
