net: dsa: b53: fix an off by one in checking "vlan->vid"
commit 8e4052c32d6b4b39c1e13c652c7e33748d447409 upstream.
The > comparison should be >= to prevent accessing one element beyond
the end of the dev->vlans[] array in the caller function, b53_vlan_add().
The "dev->vlans" array is allocated in the b53_switch_init() function
and it has "dev->num_vlans" elements.
Fixes: a2482d2ce349 ("net: dsa: b53: Plug in VLAN support")
