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. Changelog: [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.
