net: dsa: Leverage core stats allocator 

With commit 34d21de99c ("net: Move {l,t,d}stats allocation to core
and convert veth & vrf"), stats allocation could be done on net core
instead of in this driver.

With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.

Remove the allocation in the DSA user network device code and leverage
the network core allocation instead.
