[PATCH] nftables: missing set cleanup in do_command_list

[Phil Oester <kernel@xxxxxxxxxxxx>]

When listing a table in interactive mode, the set list is not cleaned up.  Thus
the number of displayed sets grows with each successive listing.  Attached
patch adds the necessary list cleanup to do_command_list.
