[PATCH 4.9 24/61] powerpc/rfi-flush: Move out of HARDLOCKUP_DETECTOR #ifdef

From: Michael Ellerman <mpe@ellerman.id.au>

The backport of the RFI flush support, done by me, has a minor bug in
that the code is inside an #ifdef CONFIG_HARDLOCKUP_DETECTOR, which is
incorrect.

This doesn't matter with common configs because we enable
HARDLOCKUP_DETECTOR, but with future patches it will break the build.
So fix it.
