pinctrl: core: use dev_err_probe() when applying state

When applying a pinctrl state, -EPROBE_DEFER may be returned if
dependencies are not ready and the consumer will retry probing.

This is normal probe ordering behaviour and not a real error.
However, pinctrl core currently logs:

  "Error applying setting, reverse things back"

even when the return value is -EPROBE_DEFER, resulting in noisy
boot-time error messages.

Replace dev_err() with dev_err_probe() to handle -EPROBE_DEFER
consistently and suppress error logging for deferred probes.

No functional change intended.
