OPP: OF: Fix an OF node leak in _opp_add_static_v2()

Browse Source 
[ Upstream commit 1d38eb7f7b ]

_opp_add_static_v2() leaks the obtained OF node reference when
_of_opp_alloc_required_opps() fails. Add an of_node_put() call in the
error path.

Fixes: 3466ea2cd6 ("OPP: Don't drop opp->np reference while it is still in use")
