After the commit 6c11dc060427 ("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...

Fixes: df2d8213d9e3 ("hisi_sas: use platform_get_irq()")

The patch is against the 'for-next' branch of Martin Petgersen's 'scsi.git'
repo.

Personally I would drop the fixes tag. I am almost sure that this HW is 
not used any longer. And I don't see a point in this change being picked 
up by stable.

Applied to 5.14/scsi-staging, thanks!
