x86/irq: Move IS_ERR_OR_NULL() check into common do_IRQ() code
Both the 64bit and the 32bit handle_irq() implementation check the irq descriptor pointer with IS_ERR_OR_NULL() and return failure. That can be done simpler in the common do_IRQ() code. This reduces the 64bit handle_irq() function to a wrapper around generic_handle_irq_desc(). Invoke it directly from do_IRQ() to spare the extra function call.
