Description of problem: 
Sets with quota elements are possible from the packet path in RHEL9 but impossible from the older nft that ships with RHEL9

Version-Release number of selected component (if applicable):
nftables-1.0.4-10.el9_1.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Use nft -f to load the following
ROOT rhel9 ~% cat /etc/sysconfig/nftables
table ip filter {
        set outbound_quota {
                type ipv4_addr
                size 65535
                flags dynamic
                elements = { 10.0.0.44 quota over 200 mbytes }
        }
}

Actual results:
ROOT rhel9 ~% nft -f /etc/sysconfig/nftables
/etc/sysconfig/nftables:6:40-44: Error: syntax error, unexpected quota, expecting comma or '}'
                elements = { 10.0.0.44 quota over 200 mbytes }
                                       ^^^^^
Expected results:
The element should load with nft $?=0

Additional info:
Loading the same element is possible in RHEL9 via the packet path
        chain OUTPUT {
                type filter hook output priority filter; policy accept;
                add @outbound_quota { ip saddr quota over 200 mbytes } drop
        }

When I build and install nftables-1.0.7-1.fc39.src.rpm from Fedora rawhide, the problem goes away and the element with a quota loads successfully via nft -f.
