commit e37c2cf299b61ce18f62852f6c5624c27829b610
Author: Florian Weimer <fweimer@redhat.com>

Move _dl_open_check to its original place in dl_open_worker
This reverts the non-test change from commit d0093c5cefb7f7a4143f
("Call _dl_open_check after relocation [BZ #24259]"), given that
the underlying bug has been fixed properly in commit 61b74477fa7f63
("Remove all loaded objects if dlopen fails, ignoring NODELETE
[BZ #20839]").
Tested on x86-64-linux-gnu, with and without --enable-cet.
