irq: remove >= nr_irqs checking with config_have_sparse_irq
remove irq limit checks - nr_irqs is dynamic and we expand anytime. v2: fix checking about result irq_cfg_without_new, so could use msi again v3: use irq_desc_without_new to check irq is valid Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
