powerpc: Fix fesetexceptflag [BZ#17885]
This patch fixes a bug introduced by 18f2945ae9216cfc, where it optimizes
the FPSCR set by just issuing a mtfs instruction if new flag is different
from older one. The issue is a typo, where the new flag should the the
new value, instead of the old one.
It fixes BZ#17885.
