sparc64: Fix stack debugging IRQ stack regression.
[ Upstream commit 166e553a575f09485f6d0df8a1ef3c5991f7d953 ]
Commit 4f70f7a91bffdcc39f088748dc678953eb9a3fbd
(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.
