OPP: Fix cleanup ordering

Browse source

Commit 173e02d674 ("OPP: Initialize scope-based pointers inline")
added initialization for all pointers. In some cases, the ordering was
changed so that *opp_table was initialized after *opp. This also changes
the order of the registered cleanup functions.

When the cleanup happens, this can cause use-after-free errors when the
last reference is released and the release function _opp_kref_release
tries to access the already freed opp->opp_table.

Initialize *opp_table before *opp again to fix this and ensure the
correct cleanup order.
