[PATCH v2] thermal: intel: powerclamp: Simplify idle_inject_update()

[Thorsten Blum <blum@kernel.org>]

Drop the local update variable and call idle_inject_set_duration()
directly instead. Also return !should_skip directly.

Signed-off-by: Thorsten Blum <blum@kernel.org>

Changes in v2:
- Call get_run_time() after powerclamp_adjust_controls() as before and
  as suggested by Sashiko [1]
- v1: https://lore.kernel.org/r/20260828184354.39423-2-blum@kernel.org/
