Leon Romanovsky 437ebfd90a devlink: Count struct devlink consumers 
The struct devlink itself is protected by internal lock and doesn't
need global lock during operation. That global lock is used to protect
addition/removal new devlink instances from the global list in use by
all devlink consumers in the system.

The future conversion of linked list to be xarray will allow us to
actually delete that lock, but first we need to count all struct devlink
users.

The reference counting provides us a way to ensure that no new user
space commands success to grab devlink instance which is going to be
destroyed makes it is safe to access it without lock.
