update_engine: check pointer for nullptr 

Member processor_ in ScopedActionCompleter is a raw pointer that is not
owned by ScopedActionCompleter. However in ScopedActionCompleter's
d'tor, it assumes processor_ is not nullptr and call its ActionComplete
function.

Add a CHECK() in c'tor making sure the object in the first place is not nullptr.

BUG=None
TEST=emerge-kefka update_engine, unittest
