Rusty Russell fcc5c4a2fe x86: avoid theoretical spurious NMI backtraces with CONFIG_CPUMASK_OFFSTACK=y 
In theory (though not shown in practice) alloc_cpumask_var() doesn't zero
memory, so CPUs might print an "NMI backtrace for cpu %d" once on boot.

(Bug introduced in fcef8576d8).

[ Impact: avoid theoretical syslog noise in rare configs ]
