[PATCH 3/3] media: i2c: ov5647: propagate pwdn GPIO errors

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

devm_gpiod_get_optional() may return -EPROBE_DEFER or other errors,
but ov5647_probe() currently converts them to -EINVAL.

Use dev_err_probe() to propagate the original error from the pwdn GPIO
lookup.

Fixes: b050791d287a ("media: ov5647: Add support for PWDN GPIO.")
