Linux 5.17 compat: GENHD_FL_EXT_DEVT / GENHD_FL_NO_PART_SCAN
As of the 5.17 kernel the GENHD_FL_EXT_DEVT flag has been removed
and the GENHD_FL_NO_PART_SCAN flag renamed GENHD_FL_NO_PART. Update
zvol_alloc() to set GENHD_FL_NO_PART for the newer kernels which
is sufficient. The behavior for prior kernels remains unchanged.
