utilities: On RHEL 7 systems clean up after upgrade
When upgrading from older versions of OVS that used the built-in geneve
kernel module on RHEL 7 systems to newer versions that use the 'compat'
vport_geneve and vport_vxlan drivers we need to clean up some cruft
that might have been left over after the upgrade.
Remove any genev_sys_6081 and vxlan_sys_4789 interfaces and then if
the RHEL 7 geneve or vxlan built-in drivers are loaded remove them
before loading the new drivers.
Removing the geneve and vxlan built-in drivers will prevent occurrences
of the "unassociated datapath" errors that can sometimes occur in some
environments.
