KVM: PPC: Book3E: Fix CONFIG_TRACE_IRQFLAGS support
32-bit does not trace_irqs_off() to match the trace_irqs_on() call in
kvmppc_fix_ee_before_entry(). This can lead to irqs being enabled twice
in the trace, and the irqs-off region between guest exit and the host
enabling local irqs again is not properly traced.
64-bit code does call this, but from asm code where volatiles are live
and so incorrectly get clobbered.
Move the irq reconcile into C to fix both problems.
