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)
