Tejun Heo 344576fa6a sched_ext: Improve logging around enable/disable ...

sched_ext currently doesn't generate messages when the BPF scheduler is
enabled and disabled unless there are errors. It is useful to have paper
trail. Improve logging around enable/disable:

- Generate info messages on enable and non-error disable.

- Update error exit message formatting so that it's consistent with
  non-error message. Also, prefix ei->msg with the BPF scheduler's name to
  make it clear where the message is coming from.

- Shorten scx_exit_reason() strings for SCX_EXIT_UNREG* for brevity and
  consistency.

v2: Use pr_*() instead of KERN_* consistently. (David)
