      .Fixes bug that caused update failures in environments with SR-IOV enabled Compute nodes

      Before this bug fix, during updates to a new maintenance releases of RHOSP 17.1 in environments with SR-IOV enabled Compute nodes, `os-net-config-sriov` failed with the error "KeyError:drivers_autoprobe" on the SR-IOV enabled Compute nodes.

      Now the error does not occur or cause an update failure.

      To Reproduce Steps to reproduce the behavior:

      1. Upgrade SRIOV enabled compute from RHOSP 17.1.3 to 17.1.4
      2. Expect VFs to be up but none found
      3. Check failed services and find this error for sriov_config.service:
