[PATCH v2] iio: resolver: ad2s1200: use dev_err_probe()

[Vojtěch Krátký]

Use dev_err_probe() instead of dev_err() to simplify the error path
and cleanly handle deferred probing.

Signed-off-by: Vojtěch Krátký <vo.kratky@xxxxxxxxx>

Changes in v2:
  - Removed curly brackets
  - aligned the error message with the parenthesis
