xen: sched: fix spinlock issue in schedule_cpu_switch().

Commit 94734ab7c3f5 ("xen: sched: close potential races
when switching scheduler to CPUs") buggily replaced a call
to pcpu_schedule_lock_irq() with just pcpu_schedule_lock(),
causing the relevant irq_safe vs. non-irq_safe ASSERT()
in check_lock() to trigger.

Fix that.
