crypto: qat - relocate and rename adf_sriov_prepare_restart()

Browse source 
The function adf_sriov_prepare_restart() is used in adf_sriov.c to stop
and shutdown a device preserving its configuration.

Since this function will be re-used by the logic that allows to
reconfigure the device through sysfs, move it to adf_init.c and rename
it as adf_dev_shutdown_cache_cfg();
