powerpc/tau: Remove duplicated set_thresholds() call

[ Upstream commit 420ab2bc7544d978a5d0762ee736412fe9c796ab ] The commentary at the call site seems to disagree with the code. The conditional prevents calling set_thresholds() via the exception handler, which appears to crash. Perhaps that's because it immediately triggers another TAU exception. Anyway, calling set_thresholds() from TAUupdate() is redundant because tau_timeout() does so.
