transporthandler: Fix for invalid VLAN id

Issue: Set LAN configuration, allowing invalid VLAN ID's and giving
exception when user trying to set VLAN.

Fix: Add condition to return proper error for invalid VLAN ID's and add
a condition to skip exception temporarily.

Tested:
Verified using ipmitool raw commands
Command: ipmitool raw 0x0c 0x01 0x1 0x14 0x00 0x80 //Set Lan, vlan id=0
Response: Unable to send RAW command (channel=0x0 netfn=0xc lun=0x0

Command: ipmitool raw 0x0c 0x01 0x1 0x14 0xff 0x8f
                       //Set Lan, vlan id=4095
