yanger: expand VLAN ranges from bridge global output

bridge -j vlan global show can return VLAN ranges as
{"vlan": 1, "vlanEnd": 3} instead of individual entries.
The vlans dict was only keyed on the start value, causing
port VLANs 2 and 3 to be reported as "Unexpected".

Also fix typo in error message (brpvlans -> brpvlan).
