Subject: [PATCH net-next 2/2] net: dsa: loop: Initialize err in dsa_loop_vlan_dump

Dan's static checker reported the following:

	drivers/net/dsa/dsa_loop.c:223 dsa_loop_port_vlan_dump()
	error: uninitialized symbol 'err'.

which could happen if we do hit the continue statement for each iteration of
the loop. Initialize err to 0 here.
