irq: mips: simplify do_domain_IRQ()
There's no need fpr arch/mips's do_domain_IRQ() to open-code the NULL check performed by handle_irq_desc(), nor the resolution of the desc performed by generic_handle_domain_irq().
Use generic_handle_domain_irq() directly, as this is functioanlly equivalent and clearer.
There should be no functional change as a result of this patch.
