[OpenAFS] Salvageserver 1.6.1-3+deb7u1 core dump

[Harald Barth]

On master, this looks like

		    opr_Verify(afs_dir_Delete(&dh, "..") == 0);
		    opr_Verify(afs_dir_Create(&dh, "..", &pa) == 0);

I guess that opr_Verify is some new fancy name for Assert?
Same patch for master as for 1.6.9 needed?

Harald.
