[ Upstream commit 53669ff591d4deb2d80eed4c07593ad0c0b45899 ]
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.
