crypto: qat - fix function parameters descriptions

Fix description of function parameters. This is to fix the following
warnings when compiling the driver with W=1:

    drivers/crypto/qat/qat_common/adf_sriov.c:133: warning: Function parameter or member 'numvfs' not described in 'adf_sriov_configure'
    drivers/crypto/qat/qat_common/adf_dev_mgr.c:296: warning: Function parameter or member 'pci_dev' not described in 'adf_devmgr_pci_to_accel_dev'
    drivers/crypto/qat/qat_common/adf_dev_mgr.c:296: warning: Excess function parameter 'accel_dev' description in 'adf_devmgr_pci_to_accel_dev'
