As per 802.1q,valid VLAN ID should be 0-4095

Issue: In Set LAN configuration, able to set VLAN ID out its range.

Fix: Added proper conditions to validate the request.

Tested:

//Setting the VLAN with invalid VLAN ID (4096)
ipmitool -I lanplus -U root -P 0penBmc -H <ip> raw 0x0c 0x01 0x01 0x14 0x00 0x90
0xCC //Invalid data field in request

//Setting the VLAN ID reserved bits with VLAN ID disable
ipmitool -I lanplus -U root -P 0penBmc -H <ip> raw 0x0c 0x01 0x01 0x14 0x00 0x70
0xCC //Invalid data field in request

//Setting the VLAN ID reserved bits with VLAN ID enabled
ipmitool -I lanplus -U root -P 0penBmc -H <ip> raw 0x0c 0x01 0x01 0x14 0x00 0xf0
0xCC //Invalid data field in request
