segtree: Check ranges when deleting elements
Make sure any intervals to delete actually exist, otherwise reject the
command. Without this, it is possible to mess up rbtree contents:
| # nft list ruleset
| table ip t {
| set s {
| type ipv4_addr
| flags interval
| auto-merge
| elements = { 192.168.1.0-192.168.1.254, 192.168.1.255 }
| }
| }
| # nft delete element t s '{ 192.168.1.0/24 }'
| # nft list ruleset
| table ip t {
| set s {
| type ipv4_addr
| flags interval
| auto-merge
| elements = { 192.168.1.255-255.255.255.255 }
| }
| }
