netfilter: nf_tables: No need to check chain existence when tracing
nft_trace_notify() is called only from __nft_trace_packet(), which assigns its parameter 'chain' to info->chain. __nft_trace_packet() in turn later dereferences 'chain' unconditionally, which indicates that it's never NULL. Same does nft_do_chain(), the only user of the tracing infrastructure. Hence it is safe to assume the check removed here is not needed.
