eina: work around current strange behavior seen in eina_cow.

This is not perfect, it will just limit the propagation of the problem
for some time. Yes, it does hide it under the carpet, but that's better
than having a crash. Problem seems to be in Eina_Hash, but is really
difficult to reproduce and fix for the moment.
