x86/fpu: Don't set TIF_NEED_FPU_LOAD for PF_IO_WORKER threads
We don't set it on PF_KTHREAD threads as they never return to userspace,
and PF_IO_WORKER threads are identical in that regard. As they keep
running in the kernel until they die, skip setting the FPU flag on them.
More of a cosmetic thing that was found while debugging and
issue and pondering why the FPU flag is set on these threads.
