genirq: Add might_sleep() to disable_irq()
With the introduction of threaded interrupt handlers, it is virtually never safe to call disable_irq() from non-premptible context. Thus: Update the documentation, add an explicit might_sleep() to catch any offenders. This is more obvious and straight forward than the implicit might_sleep() check deeper down in the disable_irq() call chain.
