ASM-5512 FCoE VLAN is getting removed during untagging on PXE VLAN and on retry

While adding / adding new vlans to IOA interface all the existing VLANs are getting removed first. This has few issues
- Network traffic coming out of server facing port will be disturbed momentarily
- FCoE network will be dropped unless network interface is restarted or server is rebooted
