    Set NODELETE flag after checking for NULL pointer

    The commit b632bdd3 moved the setting of the DF_1_NODELETE flag earlier
    in the dl_open_worker function. However when calling dlopen with both
    RTLD_NODELETE and RTLD_NOLOAD, the pointer returned by _dl_map_object is
    NULL. This condition is checked just after setting the flag, while it
    should be done before. Fix that.

        [BZ #19810]
        * elf/dl-open.c (dl_open_worker): Set DF_1_NODELETE flag later.
        * elf/tst-noload.c: New test case.
        * elf/Makefile (tests): Add tst-noload.
