Fix bug with double unload on unsuccessful dlopen

In the case of unsuccessful dlopen the failure guard is triggered
for two namespaces which leads to double unload.

Also update soinfo_free to abort in case when linker tries to free same
soinfo for the second time - this makes linker behavior less undefined.
