commit eb8333673e1ebc2418980b664a84c91b4e98afc4 upstream.

This is an error path so set the error code.  Smatch complains about the
current code:

    drivers/opp/core.c:2660 dev_pm_opp_set_config()
    error: uninitialized symbol 'ret'.

Fixes: e37440e7e2 ("OPP: Call dev_pm_opp_set_opp() for required OPPs")
