powerpc/pseries: Use irq_has_action() in eeh_disable_irq()
Rather than open-coding our own check, use irq_has_action()
to check if an irq has an action - ie. is "in use".
irq_has_action() doesn't take the descriptor lock, but it
shouldn't matter - we're just using it as an indicator
that the irq is in use. disable_irq_nosync() will take
the descriptor lock before doing anything also.
