[PATCH v2 08/10] vz: remove vzDriverLock/Unlock function

[Maxim Nestratov <mnestratov@xxxxxxxxxxxxx>]

We don't need them anymore as all pointers within vzDriver structure
are not changed during the time it exists.
Where we still need to synchronize we use virObjectLock/Unlock as far
as vzDriver is lockable object.
