MIPS: Fix GCC-4.6 'set but not used' warning in signal*.c
GCC-4.6 can find more unused code than previous versions could. In the case of protected_restore_fp_context{,32}, the variable tmp is really used. Its use is tricky in that we really care about the side effects of the __put_user() calls. So we must mark tmp with __maybe_unused to quiet the warning.
