sched/core: Fix a missed update of user_cpus_ptr
Since commit 8f9ea86fdf99 ("sched: Always preserve the user requested
cpumask"), a successful call to sched_setaffinity() should always save
the user requested cpu affinity mask in a task's user_cpus_ptr. However,
when the given cpu mask is the same as the current one, user_cpus_ptr
is not updated. Fix this by saving the user mask in this case too.
Fixes: 8f9ea86fdf99 ("sched: Always preserve the user requested cpumask")
