      MigrationSourceManager takes a CSR lock and then calls checkCollectionIdentity, which takes a CSR lock again.

      After SERVER-90798 the CSR is not reentrant anymore, so this will deadlock. We should pass the Coll and CSR locks to checkCollectionIdentity instead of letting it take them again.
