Interrupt entry sets the soft mask to IRQS_ALL_DISABLED to match the hard irq disabled state. So when should_hard_irq_enable() returns true because we want PMI interrupts in irq handlers, MSR[EE] is enabled but PMIs just get soft-masked. Fix this by clearing IRQS_PMI_DISABLED before enabling MSR[EE]. This also tidies some of the warnings, no need to duplicate them in both should_hard_irq_enable() and do_hard_irq_enable().
