[PATCH] OPP: Properly propagate error along when failing to get icc_path

[Andrew Halaney <ahalaney@redhat.com>]

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.

This slip up was totally my fault, apologies. I've got a "dirty"
working tree (where I made this enhancement while debugging) and a clean
tree for submitting patches along the way. It looks like I made a slight
change in the patch that was sent in the clean tree, then rebuilt and
tested the dirty tree and sent it off.

Won't happen again, embarrassed to admit I sent a patch that was not
properly tested but oh well. Here's a fix.

Thanks,
Andrew
