    features/quota: make writes short when the entire write cannot fit into available space.
    
    This patch aims to prevent creation of infinite zero byte sized files
    due to amount of storage available before exceeding quota limit
    being less than write sizes. Imagine x bytes of storage is available
    before we exceed quota limit and quota enforcer is receiving writes of
    size y and (y > x). In this scenario, if we run a shell script like:
    
       # for i in $(seq 1 10); do dd if=/dev/zero of=$i bs=y count=1; done
    
    Then, we would end up with 10 zero byte sized files, because we allow
    only complete writes and all writes will fail because of lack of space.
    However, creates succeed since a create itself will consume zero
    bytes. In this pattern of creates and writes, size of volume would
    never grow and x bytes of space will always be available and we can
    end up with an infinite number of zero byte sized files.
