irq: Improve a bit softirq debugging
do_softirq() has a debug check that verifies that it is not nesting
on softirqs processing, nor miscounting the softirq part of the preempt
count.
But making sure that softirqs processing don't nest is actually a more
generic concern that applies to any caller of __do_softirq().
Do take it one step further and generalize that debug check to
any softirq processing.
