Added a check for OVN SB schema, looking for "virtual_parent" in "Port_Binding" table (added in OVN SB schema 2.5). This patch removes the code to support OVN without virtual ports. It is assumed that "virtual_parent" field is present in "Port_Binding" table. Closes-Bug: #1949496 Change-Id: I3d01f58dca570537b5e754b331ca4809a7161ae2
