This failure is most likely an error return from VFS_VGET() caused by a bogus d_fileno that was truncated to 32bits. This patch fixes the server so that it will return directory postop attributes for the failure. It does not fix the underlying issue caused by d_fileno being uint32_t when a file system like ZFS generates a fileno that is greater than 32bits.
