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.
Fixes: bc06a9e08742 ("genirq: Use hlist for managing resend handlers")
