[PATCH nft] limit: display default burst when listing ruleset

[Pablo Neira Ayuso <pablo@netfilter.org>]

Default burst for limit is 5 for historical reasons but it is not
displayed when listing the ruleset.

Update listing to display the default burst to disambiguate.

man nft(8) has been recently updated to document this, no action in this
front is therefore required.
