      Description

      Commit 1fc013f90175d1e50d7a22b404ad6abd31a43e38 in LU-5319 failed to restore the original flags ptlrpc_connect_import failure. Handle this gracefully so the system doesn't LBUG.

      I'll submit a patch to gerrit when I get a chance to fix my keys. In the mean time the diff is here for reference.
