Add a jump target so that a bit of exception handling can be better reused
at the end of this function.
This issue was detected by using the Coccinelle software.

IMHO, it's really confusing that "irq" contains the error code, not "error".
I think it would have been equally confusing if 'error' was assigned to
'ndev->irq', etc. It's just the duality of the result of these functions that
makes them confusing...
Especially when jumping to a meaningless label named "failure_indication"
("irq_failure" would be more intuitive).
Yeah, the label sucks. :-)
So I prefer the original code, regardless of the label name.
On the 2nd thought, the patch can be fixed up and then merged.
