powerpc/64s: Fix RFI flush dependency on HARDLOCKUP_DETECTOR
The backport of commit aa8a5e0062ac ("powerpc/64s: Add support for RFI
flush of L1-D cache"), incorrectly placed the new RFI flush code
inside an existing #ifdef CONFIG_HARDLOCKUP_DETECTOR block.
This has the obvious effect of requiring HARDLOCKUP_DETECTOR to be
enabled in order for RFI flush to be enabled, which is a bug.
Fix it by moving the #endif up to where it belongs.
