Frederic Weisbecker be6e101644 irq: Optimize call to softirq on hardirq exit 
Before processing softirqs on hardirq exit, we already
do the check for pending softirqs while hardirqs are
guaranteed to be disabled.

So we can take a shortcut and safely jump to the arch
specific implementation directly.
