Don't ignore errors from begin operation.

This fixes a bug introduced by
9221bff2f13451ef330135bb32ea96de2a8b09cc which invoked authorization
checks after begin operation, while ignoring any errors returned by
that operation. This CL restrores the correct order: authorization
checks are followed by begin operation.
