x86, hw_nmi: Move backtrace_mask declaration under ARCH_HAS_NMI_WATCHDOG
backtrace_mask has been used under the code context of
ARCH_HAS_NMI_WATCHDOG. So put it into that context.
We were warned by the following warning:
arch/x86/kernel/apic/hw_nmi.c:21: warning: ‘backtrace_mask’ defined but not used
