powerpc: Fix __fesetround_inline_nocheck on POWER9+ (BZ 31682)
The e68b1151f7460d5fa88c3a567c13f66052da79a7 commit changed the
__fesetround_inline_nocheck implementation to use mffscrni
(through __fe_mffscrn) instead of mtfsfi. For generic powerpc
ceil/floor/trunc, the function is supposed to disable the
floating-point inexact exception enable bit, however mffscrni
does not change any exception enable bits.
This patch fixes by reverting the optimization for the
__fesetround_inline_nocheck.
Checked on powerpc-linux-gnu.
