OPP: Properly propagate error along when failing to get icc_path

fa155f4f8348 ("OPP: Use dev_err_probe() when failing to get icc_path")
failed to actually use the error it was trying to log:

    smatch warnings:
    drivers/opp/of.c:516 dev_pm_opp_of_find_icc_paths() warn: passing zero to 'dev_err_probe'

Make sure to use the right error and pass it along.
