genirq: Split irq_set_affinity() so it can be called with lock held.
The .irq_cpu_online() and .irq_cpu_offline() functions may need to
adjust affinity, but they are called with the descriptor lock held.
Create __irq_set_affinity_locked() which is called with the lock held.
Make irq_set_affinity() just a wrapper that acquires the lock.
[ tglx: Changed the argument to irq_data, added a !desc check and
moved the !irq_set_affinity check where it belongs ]
