smp: quit unconditionally enabling irqs in on_each_cpu_mask().
As in commit f21afc2 ('smp.h: Use local_irq_{save,restore}() in are not already enabled. I don't know of any bugs currently caused by this unconditional local_irq_enable(), but I want to use this function in MIPS/OCTEON early boot (when we have early_boot_irqs_disabled). This also makes this function have similar semantics to on_each_cpu() which is good in itself.
