 Log Message:
 ld.elf_so: Fix one more mistake in handling _rtld_load_object.
 
 This can return NULL (meaning object not found or something went wrong
 with the object) or OBJ_ERR (meaning the object has DF_1_NOOPEN set or
 the caller passed RTLD_NOLOAD to dlopen() and the object was not
 already loaded) or a valid object.
 
 I reviewed all paths out of _rtld_load_object to make sure they
 gracefully handle all three cases (NULL, OBJ_ERR, valid object), and
 this assertion was the only path that didn't.
 
 Fixes buggy assertion added for:
 
 PR lib/59751: dlclose is not MT-safe depending on the libraries
 unloaded
 
 May fix:
 
 PR bin/60472: ld.elf_so(1) changes cause a segmentation fault in
 dlopen(3)
