    netfilter: nf_tables: allow to fetch set elements when table has an owner
    
    [ Upstream commit 92f3e96d642f5e05b9dc710c06fedc669f1b4f00 ]
    
    NFT_MSG_GETSETELEM returns -EPERM when fetching set elements that belong
    to table that has an owner. This results in empty set/map listing from
    userspace.
