Subject: [PATCH] crypto: qat - remove empty sriov_configure()

Git-commit: 462584ca17b4ca85721475cf2744d3229d4006cd

Patch-mainline: v5.15-rc1

References: jsc#PED-1073

Remove the empty implementation of sriov_configure() and set the

sriov_configure member of the pci_driver structure to NULL.

This way, if a user tries to enable VFs on a device, when kernel and

driver are built with CONFIG_PCI_IOV=n, the kernel reports an error

message saying that the driver does not support SRIOV configuration via

sysfs.
