    [OVS] Make QoS OVS agent deletion operations more resilient

    When a Port is deleted, the QoS extension will reset any rule (QoS
    and Queue registers) applied on this port or will reset the
    related Interface policing parameters.

    If the Port and the related Interface are deleted during the QoS
    extension operation, those commands will fail. This patch makes those
    operations more resiliant by not checking the errors when writing on
    the Port or the Interface register.

    NOTE: this patch is squashed with [1]. That will fix the problem
    with empty "vsctl" transactions when using this OVS DB implementation.
