The test bot already said it, but ptr is passed to
hfi_session_set_property() uninitialized. And as can be expected the
call returns -EINVAL on my board.
Looking at other uses of HFI_PROPERTY_CONFIG_VENC_REQUEST_SYNC_FRAME I
see that the packet sent to the firmware does not have room for an
argument, so I tried to pass NULL but got the same result.
