Subject: [PATCH net-next 1/2] net: dsa: loop: Fix uninitialized pvid variable

Dan's static analyzer reported the following:

	drivers/net/dsa/dsa_loop.c:181 dsa_loop_port_vlan_del()
	error: XXX uninitialized symbol 'pvid'.

we were missing the assignment of pvid to ps->vid, so add that.

Fixes: 98cd1552ea27 ("net: dsa: Mock-up driver")
