[nf PATCH] net: nf_tables: Support auto-loading for inet nat

[Phil Sutter]

Trying to create an inet family nat chain would not cause
nft_chain_nat.ko module to auto-load due to missing module alias. Add a
proper one with hard-coded family value 1 for the pseudo-family
NFPROTO_INET.

Changes since RFC:
- Go with hard-coding the value for now like in nf_flow_table_inet.c.
- Adjust subject and commit message a bit.

Applied, thanks Phil.
