hujun5 791c1a4ab5 sched/setpriority: handle CPU affinity change for running task 
When a running task changes its affinity on SMP and is no longer eligible to run on the current CPU, merely delivering an equal-priority scheduling request can leave the task in g_readytorun while the target CPU remains idle. The task then never runs again.

Remove the task from its current CPU, add it back to the ready-to-run list so a suitable CPU is selected, and perform the context switch unconditionally. This ensures the task is migrated according to its updated affinity.
