network_info cache should be cleared before being rescheduled

If an instance fails to boot due to a non-networking error the instance
then gets rescheduled and launched on another compute node. In these cases
deallocate_for_instance() is called which deletes the network ports
allocated though the info_cache for the instance is never cleared. This patch
adds a call to update_instance_cache_with_nw_info() which causes the cache
to get cleared out. Note: the cache is only cleared if the instance hasn't
been marked for deletion. This is due to how instance_info_cache_update()
is implemented.
