ext4: fix project quota accounting without quota limits enabled
We should always transfer quota accounting, regardless of whether
quota limits are enabled.
Steps to reproduce:
# mkfs.ext4 /dev/sda4 -O quota,project
# mount /dev/sda4 /mnt/test
# cp /bin/bash /mnt/test
# chattr -p 123 /mnt/test/bash
# quota -v -P 123
