[nft PATCH 3/5] cache: Relax chain_cache_dump filter application

[Phil Sutter <phil@nwl.cc>]

While populating chain cache, a filter was only effective if it limited
fetching to both a table and a chain. Make it apply to 'list chains'
command as well which at most specifies a family and table.

Since the code is OK with filter->list fields being NULL, merely check
for filter to be non-NULL (which is the case if nft_cache_update() is
called by nft_cmd_enoent_chain()).
