torture: Stop hanging on panic
By default, the "panic" kernel parameter is zero, which causes the kernel
to loop indefinitely after a panic(). The rcutorture scripting will
eventually kill the corresponding qemu process, but only after waiting
for the full run duration plus a few minutes. This works, but delays
notifying the developer of the failure.
This commit therefore causes the rcutorture scripting to pass the
"panic=-1" kernel parameter, which caused the kernel to instead
unceremoniously shut down immediately. This in turn causes qemu to
terminate, so that if all of the runs in a given batch panic(), the
rcutorture scripting can immediately proceed to the next batch.
