[PATCH v2 09/14] sched_ext: Make handle_lockup() propagate scx_verror() result

[Tejun Heo]

handle_lockup() currently calls scx_verror() but ignores its return value,
always returning true when the scheduler is enabled. Make it capture and return
the result from scx_verror(). This prepares for hardlockup handling.
