[libvirt] [PATCH 01/18] vz: remove disk cache mode hunk

[Nikolay Shirokovskiy]

This code was added as a part of huge patch that moves driver
from working with prlctl to vz sdk so there is no good explanation
why this is done this way. The problem that it is not correct.
vz sdk cache mode parameter affects all domain disks while this hunk
resets its on every disk to a new value.
