Bug description:
  On a system with lots of VFs and PFs we get these logs:

  WARNING oslo.service.loopingcall [-] Function 'neutron.plugins.ml2.drivers.mech_sriov.agent.sriov_nic_agent.SriovNicSwitchAgent._report_state' run outlasted interval by 29.67 sec
  WARNING oslo.service.loopingcall [-] Function 'neutron.plugins.ml2.drivers.mech_sriov.agent.sriov_nic_agent.SriovNicSwitchAgent._report_state' run outlasted interval by 45.43 sec
  WARNING oslo.service.loopingcall [-] Function 'neutron.plugins.ml2.drivers.mech_sriov.agent.sriov_nic_agent.SriovNicSwitchAgent._report_state' run outlasted interval by 47.64 sec
  WARNING oslo.service.loopingcall [-] Function 'neutron.plugins.ml2.drivers.mech_sriov.agent.sriov_nic_agent.SriovNicSwitchAgent._report_state' run outlasted interval by 23.89 sec
  WARNING oslo.service.loopingcall [-] Function 'neutron.plugins.ml2.drivers.mech_sriov.agent.sriov_nic_agent.SriovNicSwitchAgent._report_state' run outlasted interval by 30.20 sec

  
  Depending on the agent_down_time configuration, this can cause the Neutron server to think the agent has died.

  
  This appears to be caused by blocking on the eswitch manager every time to get a device count to include in the state report.
