libnftables: Print errors before freeing commands
Commands may contain data printed by an error record, so make sure cmd_free() is not called before erec_print_list() has returned. Fixes: 778de37d82e7b ("libnftables: Keep cmds list outside of parser_state") Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
