genirq: Initialize resend_node hlist for all interrupt descriptors
For a CONFIG_SPARSE_IRQ=n kernel, early_irq_init() is supposed to initialize all interrupt descriptors. It does except for irq_desc::resend_node, which ia only initialized for the first descriptor. Use the indexed decriptor and not the base pointer to address that.
