powerpc/dtrace: Actually fix stack traces

Fix stack unwinding such that requesting N stack frames in lockstat will
actually give you N frames, not anywhere from 0-3 as had been before.

lockstat prints the mutex function instead of the caller as the reported
locker, but the stack frame is detailed enough to find the real caller.

MFC after: 2 weeks
