drm: panel: orisetech: improve error handling during probe

Use dev_err_probe() helper as directed by core driver model to handle
driver probe error. Use standard helper defined at drivers/base/core.c
to maintain code consistency.

Inspired by,
commit a787e5400a1ce ("driver core: add device probe log helper")
