Felix Fietkau 6300e59fa9 MIPS: Fix sched_getaffinity with MT FPAFF enabled ...

commit 1d62d73755 upstream.

p->thread.user_cpus_allowed is zero-initialized and is only filled on
the first sched_setaffinity call.

To avoid adding overhead in the task initialization codepath, simply OR
the returned mask in sched_getaffinity with p->cpus_allowed.
