Commit Message

These log messages are wrong because _of_get_opp_desc_node() returns
an operating-points-v2 node.

Commit a6eed752f5fb ("PM / OPP: passing NULL to PTR_ERR()") fixed
static checker warnings, and reworded the messages at the same time
(but the latter was not mentioned in the git-log).

Restore the correct messages, dropping __func__.  We can grep the
message string, so the function name would not carry much value.

The error messages are very generic and it can get tricky to grep for them in
the source code..

I would prefer keeping function name in the print message.
