[PATCH v2 3/3] genirq: remove unnedded NULL check in __irq_domain_[de]activate_irq()

[Kemeng Shi]

Both __irq_domain_deactivate_irq() and __irq_domain_activate_irq() are
static functions whose callers always pass a valid irq_data pointer, as
evidenced by the callers either dereferencing it or performing a NULL
check before invoking these functions. The redundant NULL check on
irq_data can therefore be removed.
