x86/hyperv: Fix build for CONFIG_KEXEC_CORE=n
Recent changes in the Hyper-V driver broke the build when CONFIG_KEXEC_CORE is not set:
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'
Decorate all kexec related code with #ifdef CONFIG_KEXEC_CORE.
