netfilter: nf_tables: fix chain filter in nf_tables_dump_rules()

Browse source

[ Upstream commit 24c0df82ef ]

ctx->chain may be null now that we have very large object names,
so we cannot check for ctx->chain[0] here.

Fixes: b7263e071a ("netfilter: nf_tables: Allow table names of up to 255 chars")
