sparc64: Handle stack trace attempts before irqstacks are setup.
[ Upstream commit 6f63e781eaf6a741fc65f773017154b20ed4ce3b ]
Things like lockdep can try to do stack backtraces before
the irqstack blocks have been setup. So don't try to match
their ranges so early on.
Also, remove unused variable in save_stack_trace().
