xtables-restore: init table before processing policies
*filter
:INPUT DROP [32:4052]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [0:0]
-A OUTPUT
COMMIT
will be restored with ACCEPT policies. When
-A OUTPUT is processed, the OUTPUT chain isn't found in the chain cache,
so the table is re-created with ACCEPT policies, which overrides the
earlier DROP policies.
A better fix would be to add the policy setting to the chain cache
but it seems we'll need a chain abstraction with refcounting first.
Fixes: 01e25e264a4c4 ("xtables: add chain cache")
