server-info: avoid calling fclose(3) twice in update_info_file()rs/misc-cppcheck-fixes

If an error occurs when or after closing the stream we call fclose(3)
again in the error handler.  The second call can exhibit undefined
behavior, so make sure to call fclose(3) at most once.  Also avoid
calling close(2) after fd has been successfully associated with the
stream, as fclose(3) has become responsible for doing that beyond
this point.

Found with Cppcheck.
