kernel/smp.c: remove cpumask_ipi
After commit 9a46ad6d ("smp: make smp_call_function_many() use logic similar to smp_call_function_single()"), cfd->cpumask is accessed only in smp_call_function_many(). So there is no more need to copy it into cfd->cpumask_ipi before putting csd into the list. The cpumask_ipi field is obsolete and can be removed.
