Bug 7295 - Incorrect handling of device transactions in clustered setting

Transactions on mounted device in clustered setting are delegated to
leader node and leader node actually configures the device.

Implementation, hovewer, depens only on one transaction at a time.
Delegated calls can interleave together, for example one node can submit
transaction of the other node.

Explicitly open a new tranasction before applying any operations to it.
