    Semantic check for proper sriov plugin configuration

    This commit adds a semantic check to host-unlock to prevent unlocking
    if the label "sriovdp=enabled" is present and there are no PCI-SRIOV
    interfaces enabled.

    Test plan

    PASS Unlock system with sriovdp label absent and 0 PCI-SRIOV
         interfaces enabled
    PASS Unlock system with sriovdp label absent and 1 PCI-SRIOV
         interface enabled
    PASS Unlock system with sriovdp label present and 0 PCI-SRIOV
         interfaces enabled
    PASS Try to unlock system with sriovdp label present and 1 PCI-SRIOV
         interface enabled (command fails)
