Pull sched_ext fixes from Tejun Heo:

 - Fix handling of migration disabled tasks in default idle selection

 - update_locked_rq() called __this_cpu_write() spuriously with NULL
   when @rq was not locked. As the writes were spurious, it didn't break
   anything directly. However, the function could be called in a
   preemptible leading to a context warning in __this_cpu_write(). Skip
   the spurious NULL writes.

 - Selftest fix on UP
