Steps to reproduce:
mkfs.btrfs <disk>
mount <disk> <mnt>
btrfs quota enable <mnt>
btrfs sub create <mnt>/subv

i=1
while [ $i -le 10000 ]
do
dd if=/dev/zero of=<mnt>/subv/data_$i bs=1K count=1
i=$(($i+1))
if [ $i -eq 500 ]
then
btrfs quota disable $mnt
fi
done
dmesg
Obviously, this warn_on() is unnecessary, and it will be easily triggered.
Just remove it.
