[NETFILTER]: nf_nat: fix hanging connections when loading the NAT module

Browse source 
When loading the NAT module, existing connection tracking entries don't
have room for NAT information allocated and packets are dropped, causing
hanging connections. They really should be entered into the NAT table
as NULL mappings, but the current allocation scheme doesn't allow this.

For now simply accept those packets to avoid the hanging connections.
