    cluster/afr: disable self-heal lock compatibility for arbiter volumes

    Problem:
    afrv2 takes locks from infinity-2 to infinity-1 to be compatible with
<=3.5.x
    clients. For arbiter volumes this leads to problems as the I/O takes full
file
    locks.

    Solution:
    Don't be compatible with <=3.5.x clients on arbiter volumes as arbiter
volumes
    are introduced in 3.7
