During vrf delete, the vxlan_info.work_list linked list was deleted which is a global list containing the SGs for all the VRFs. If two vrfs are configured, vrf a and vrf b and both has SGs assocaited with them which are inserted in the vxlan_info.work_list. Now if vrf a is deleted, it deletes the work_list also. Due to this when any SG add or del comes for vrf b it tries to access the work_list and crashes. Fix Delete the vxlan_info.work_list only when all the VRFs are terminated and unset the vxlan_info.flags so if new add cmd comes it re-allocates the work_list.
