[PATCH] sched_ext: Include remaining task time slice in error state dump

[Andrea Righi <arighi@nvidia.com>]

Report the remaining time slice when dumping task information during an
error exit.

This information can be useful for tracking incorrect or excessively
long time slices in schedulers that implement dynamic time slice logic.
