Dawei Li 5966ed9caa genirq: Initialize resend_node hlist for all interrupt descriptors ...

commit b184c8c288 upstream.

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: bc06a9e087 ("genirq: Use hlist for managing resend handlers")
