Delete virtual interface "ovs-system" before load openvswitch module

Browse Source 
When openvswitch module is loaded by modprobe in [1], if  virtual
interface "ovs-system" exists, it causes the error " modprobe:
FATAL: Module openvswitch is in use."

This patch will check "ovs-system" exists or not, then delete it
before load openvswitch module.
