crypto: qat - allow enabling VFs in the absence of IOMMU
The commit ca88a2bdd4dd ("crypto: qat - allow disabling SR-IOV VFs")
introduced an unnecessary change that prevented enabling SR-IOV when
IOMMU is disabled. In certain scenarios, it is desirable to enable
SR-IOV even in the absence of IOMMU. Thus, restoring the previous
functionality to allow VFs to be enumerated in the absence of IOMMU.
