drm/panel: ltk050h3146w: use dev_err_probe wherever possible

This is only a cosmetic change.

This replaces a hand-crafted EPROBE_DEFER handling for deciding to print
an error message with dev_err_probe.

A side-effect is that dev_err_probe also adds a debug message when it's
not EPROBE_DEFER, but this is seen as an improvement.
