Commit 6240aaad75e1 was supposed to drop the reference count to the OPP, instead it avoided more stuff if the OPP isn't found. This isn't entirely correct. We already have a frequency value available, we just couldn't align it with an OPP in case of IS_ERR(opp). Lets continue with updating thermal pressure, etc, even if we aren't able to find an OPP here. This fixes warning generated by the 'smatch' tool.
