Fix reset the vlan flags when main interface is deleted.
The dot1q_vlans & dot1ad_vlans should be reset to 0 when main interface is deleted. Otherwise, VPP will crash if the same interface index is reused without attaching the sub interface on it. Change-Id: I484d4a8892ff4241a3a32b22189746193d5f2594 Signed-off-by: Steve Shin <jonshin@cisco.com>
