powerpc: Fix power4/970 idle code regression with lockdep in commit 7230c5644188cd9e3fb380cc97dde00c464a3ba7 "powerpc: Rework lazy-interrupt handling" I introduced a regression, accidentally calling irq tracing twice and not properly restoring a clobbered register (r7) later used for writing to the MSR. This caused lockups when booting on a G5 with lockdep enabled. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
