Change function signature for creating new lock manager instances

Browse Source 
To allow a virLockManagerPtr to be created directly from a
driver table struct, replace the virLockManagerPluginPtr parameter
with a virLockDriverPtr parameter.

* src/locking/domain_lock.c, src/locking/lock_manager.c,
  src/locking/lock_manager.h: Replace plugin param with
  a driver in virLockManagerNew
