erts: Fix bug causing mbc to be deleted from cpool before it was inserted
Set IN_POOL flag _after_ mbc has been actually inserted. Earlier it did not matter if IN_POOL was set early as it was not possible to find a carrier before is was fully inserted. Now when searching pooled_list and traitor_list we must make sure a found carrier has been fully inserted into cpool before removing it.
