scsi: hisi_sas: Propagate errors in interrupt_init_v1_hw()

[ Upstream commit ab17122 ]

After commit 6c11dc0 ("scsi: hisi_sas: Fix IRQ checks") we have the
error codes returned by platform_get_irq() ready for the propagation
upsream in interrupt_init_v1_hw() -- that will fix still broken deferred
probing. Let's propagate the error codes from devm_request_irq() as well
since I don't see the reason to override them with -ENOENT...
