coverity/13696: Unchecked return value: RI.

Browse Source 
Problem    : Unchecked return value (CHECKED_RETURN) @ 2644.
Diagnostic : Real issue.
Rationale  : Other `u_save` invocations are checked, and there's no
             reason to think this invocation could not fail.
Resolution : Check and return if failed (other previous checks in the
             same function just return, without reporting error, so
             we just do the same).
