David S. Miller 166e553a57 sparc64: Fix stack debugging IRQ stack regression. ...

Commit 4f70f7a91b
(sparc64: Implement IRQ stacks.) has two bugs.

First, the softirq range check forgets to subtract STACK_BIAS
before comparing with %sp.  Next, on failure the wrong label
is jumped to, resulting in a bogus stack being loaded.
